OOOOOPs Wrote this and I guess I forgot to post it so now it's posted
As a mechanic, there's nothing to pulling the engine and tranny, just finding all the right bolts and wires to remove, TAKE PHOTOS so you can refer back to them. Keep an eye here, I'll post some valuable info to help you as I find it

I think he's passing it on to me, On my 08, I saw some play in the slave cylinder mounting, so I made a bracket to stiffen things up. I also drilled a hole in the bell so I could stick a little camera in to see what was happening inside, Lenny, one of the early group, did something to beef up the fork to the throw out bearing, but he was a fanatic and even machined the throw out bearing guide.
I would check the hydraulics first, have someone step on the clutch pedal and watch what happens at the bell. I know, you already did this, then, if memory serves me, I'm 68, you can slip the splines on the throw out shaft, make scratches and take photos of things before and after and try moving the throw out with a wrench and see if you feel any thing.
If you don't find anything, buy one of those cheap endoscope (google it) cameras and drill a hole in the top of the bell housing and see if you can spot a breaking part in the throw out linkage. you can spray some grease on the bearing too,
When I sold my 08, it was still running the original parts + the stiffener.
PM me if you want to talk.

I'm a little late with this, but look what I got to go see on the morning of the 4th.
this just one of several article about the ( Pleasant Grove, Utah Flag )google it if you want.
Really awesome, I can see it out my backdoor, especially at night when it's lit up and throws a shadow on the rocks behind it.

I hope I got that right and in the proper order, end result of dumping the Yearbens and putting the F-O-A on is an even better ride and the confidence that I can rebuild them again when I need to and every single part can be bought right here in the U.S.A., Las Vegas, Nev. If I want to change my rebound or dampening, I can,
Thanks F-O-A

Jeff,
Curious how you came up with rear shock mount placement? Is that where you had it on your last rig? What is the total travel?
With the additional weight of my 32" tires I need to adjust my rebound.
These shocks were on the yellow 08, and the seals were blown, when I bought the blue '15, they took the stock shocks off and gave them to me after putting the yearbens on, when I sold the yellow '08, I took the F-O-As off and put the new stock shocks from the blue'15 on it and kept the leaking F-O-As as spares, it's a season or two later and I need to replace the Yearbens, so this is where I'm at now.
The placement of the lower shock mount was by MY choice, my theory being that all the forces down on the swing arm should be as close to center of the wheel as possible to reduce the tendency to cause the swing arm to roll from rolling, as it did on the yellow'08 and I had to change the right swing arm because the right side tire had a bad inward lean at the top, it may have come that way and I didn't notice.
The upper mount was because I put the lower one back too far, the shock is compressed about an inch with the limit straps, So I have about 9 inches of shock travel and without taking the springs off, I can't be sure of what the wheel travel is.
As for a good ride, I think I hit my target pretty good, went for a ride yesterday and when I came to a pretty good whoop, I didn't back out of it or any thing else and was very pleased how the Trooper took it, so was the wife. I have 200# 10" over 400# 10" springs and it's been so long since I messed with the valving washers, I'm not sure how I have them set.
I uploaded a .AVI video here, it's 10 minutes of the wheel going round and round and the shock going up and down.

Some history, when I had the F-O-As on the yellow 08 Trooper, I had to run a limit strap to keep the swing arm from going down too far and hitting the axle and knocking it out of the CV, which happened a few times.
When Joyner advised me about rebuilding the Yearben, they said I could get a bit more travel by leaving a spacer out, but I would have to run limit straps again, which was my plan until I started tearing them down and saw what I had. I had to rebuild my shocks, and it became a choice between Yearben and F-O-A. I went with the F-O-As for a lot of reasons, longer travel, dual springs, easy to build. To take advantage the longer travel, I needed to move the shock mount, so I did, I moved it back by the wheel and out, oops too far, add another mount for the top that is behind the the stock mount. Tomorrow, I'll see how I did, and I'll take some photos too.
Here's a few photos of how I remounted my 10" rebuilt F-O-A 2.0" shocks with 2.5 coil over springs (200# over 400#) (and it feels about right), The limit strap is Amsteel-Blue Rope, (http://www.go2marine.com/product/38345F/samson-amsteel-blue-rope.html?WT.srch=1&WT.mc_id=gb1&utm_source=googlebase&utm_medium=productfeed&utm_campaign=googleshopping&gclid=CjwKEAjwvYPKBRCYr5GLgNCJ_jsSJABqwfw7GsayfIaI2VFV5AJMJAD1Qoe1Wojhr9ASGTsHv9qK-xoCFXPw_wcB ) so I'm sure it's strong enough!
I'm still doing finishing up things,painting, tightening and checking and need to put the deck back on and test some more.

Because UPS seems to be waiting a day to process my orders from F-O-A, meaning what should be here today or tomorrow won't be here until Monday, so I had time to figure out how Yearben shocks come apart, I could labor on and tell you, but I'll let you figure out your self if you buy them, my opinion, I'm not too proud of them, they don't lend themselves to being rebuilt because I doubt the main shaft seal probably won't be available, the rest are just O-rings, once you figure out how to get at them, they use what appears to be a special compound to seal the seal and the threads, the nut that holds valve pack in place is welded, so you can't tune them.
I think they are a one use and replace shock and mine didn't last long enough to suit me and I don't how the ride compares to the stock shock because I replaced the rear stock ones on my 08 Trooper in 09 and the fronts in 12 and when I bought the blue 2015 Trooper, I ordered it with the Yearbens, they gave me a good ride for almost 4000 miles, at which point, they were out of oil, just springs, not shocks.
I can't endorse them because I think the should last longer, I wonder how long the stock shocks would have lasted and saved me around a $1000.00.

I can not endorse Yearben Shock from you, from Joyner USA or any one else, mine failed in short order and I am unable to rebuild them, at present, there is no REBUILD kit available, so they are NOT rebuildable.
I am putting my old F-O-A shocks back on and changing the spring rate from 400 over 600 to 200 over 400 and putting seal kits in both sides,
As I was rebuilding my F-O-A Shocks, I was having problem getting the main shaft seal to go in and gave F-O-A a call plus a email with photos, while discussing MY problem, F-O-A took the time to look at my photos and once he understood my problem, the best solution was ordered.
F-O-A does get my endorsement, they are easily resealable and/or rebuildable and the kits are only a phone call away, plus the UPS time
IMHO, they must use some good quality parts, I'm still using the original orbital bearings from 2009, 7 - 8 years so far instead of failing after 1.5-2 years.
-
The lower orbital bearing came apart in less than 4000 miles?
I'm going back to my FOA shocks that I saved off my old Trooper.

HOLD OFF ON THE YEARBEN SHOCKS, BOTH OF MY REAR SHOCKS ARE NOW SPRINGS, LOST ALL THE OIL, NOT SHOCK ABSORBER ANY MORE!
AND I ONLY HAVE ~ 3500 MILES OF EASY RIDING ON THEM, I NEVER GO AIRBORNE (on purpose) and stay out of the rough stuff.
TRYING TO GET REBUILD KIT, NO LUCK SO FAR, IF AND WHEN I FIND THEM, i'LL POST

When I boought my Trooper T2, I ordered it with a few option, one being Yearben Shocks and I have been used as a reference for others to buy them also and maybe even recommended them.
NOT NOW
I'm still getting up, but when I go down to the garage, I'll take another look at my Yearben shocks and mileage, when I bought this thing, I ordered with the upgrade and I have been really happen with the ride, I had oversprung my 2008 Trooper and it would launch the rear end and also bottom out and jar my back, doesn't happen much with my 2015 and the yearben shocks, my wife is much happier with them too. I must say though that I'm seeing an oily shaft and that's what I need to go down to the garage to see if it's one or two and mileage. Have you checked prices at http://joyner-usa.com/ or Call Us Today! (480) 882.9612
Finally got around to looking at my shocks, I think the right rear is gone or going, at 3460 miles, called Brandon at Joyner USA and he's sending me a set of rebuild kits and gave me some advice, while rebuilding, lose the aluminum sleeve around the shaft, gives more travel but require the use of limit strap, which you should use any way and fill them with 140 PSI nitrogen, air will work, but! the air molecule is smaller than the nitrogen molecule, so air leaks out faster than it does with nitrogen. Personal thought, air is mostly nitrogen any way, so how does it leak out faster, or is it the O2 and CO2 part that's leaking out.
Notice the oily wetted dirt on the swing arm! and that's after I cleaned it off a few times.

Because of distracting problem with other topics, I decided to move and or copy the content from there to here. I'll see how it goes.

I sorry if YOU think "Bull Shit" is profanity and or cursing you, but sometime I just think you're full of it and get tired of reading it, This was a Joyner Trooper and other Joyners forum at one time and not a Silverbullet sales and advertisement forum, not my forum, so I can't stop you.
SO, Say what you will, I'm DONE with you! NO replies, NO answers, but I would prefer you not make sale pitches in reply to my posts.
Jeff

Granted, they recommend nitrogen, what you said is air damages valve springs, that's bullshit!!! I used to run air over oil in motorcycle forks with no damage and in the shocks that have reservoirs, the gas (air or nitrogen) doesn't even touch the oil (except for my failed Yearbens) so how can it damage valve springs????? Bull Shit!!!!!
Did you get my pm telling you not to say I'm using Yearbens on my Trooper?? I'm NOT!!!

Yearben has been making shock in Chine.6 years of making shocks. What is in the picture is the Yearben shocks. I can only sell in sets of 4 pieces.
I am sorry but this is the only way I can buy them for awhile.1,000 set of four 1 year warrant on them kits to rebuild them are aveable to rebuild them.Kinarfi said he had a small leak after 2 years. Kit are aveable to reseal them. They have made changes in the two years to improve them.
Sorry Rick
Kinarfi here, I have removed the yearben shocks!! The ones I have are NOT revalvable, the nut is welded on, there was oil in the reservoir pressure chamber and gas (air or Nitrogen) in the shock body, and no shock action, just springs at ~4000 miles, I haven't been able to get a rebuild kit, and you better figure on having to replace the shock eyes too, That's my experience, my thoughts are that they are what you pay for, CHEAP throw aways and no better the the stock shock

2scoops, from my experience, if you have oil in the intake, you may be having too much bypass around the rings, do you still have the oil/air separator mounted? FYI My '15 doesn't even have one.

They use nitrogen in shocks because it contain no moisture. So no corrosion or contaminate the in side of shocks. Never use air or you will destroy the valving in side the shocks.
I have to call "bull shit" on this statement! if air is used in shocks, even if it's 'wet', it is in the reservoir pressure tank, not in the oil, not mixed with the oil and does not contact the valving washers! Maybe it does in Yearbens, don't know, but there was a lot of oil in the pressure part of the reservoir, and there seemed to be air/or nitrogen in the oil when I drained them, but it's my understanding oil and air/nitrogen shouldn't mix in any shock.
The purpose of pressure on one side of the floating piston is to assist the oil in returning to the shock body as the shaft leaves the shock body during rebound, it keeps the oil from cavitating and adds nothing directly to the suspension and definitely doesn't damage valving washers. Not in anything I've seen.
oh yes, F-O-A Shocks are sold out of Las Vegas

Kinarfi Has them on his new trooper.
Silverbullet, DO NOT tell people I have them on my Trooper, I Don't, and I wouldn't unless you gave them to me for free, and then, I would just keep them for emergency back up, I DON'T LIKE THEM AND DON'T WANT ANYONE THINKING I DO

I measured the shocks, I had 9" of shaft showing and the limit straps are holding about an inch inside, SO! they are 10".
When I set my limit straps up, set it so I have about 1/8" separation between axle and swing arm when the wheels are off the ground, then just to see if they ever make contact, I put tape on the axle and as long as the tape looks good, no contact was made.

Can you get any information from previous owner or do you not know who it is?
I can't imagine the loss of 4 & 5 being just an adjustment, but you're beyond the realm of what I've done & i'm not a mechanic, but I have had my engine &tranny out and apart years ago.
Good luck
Jeff
