Rear Diff

Recommended Posts

I have a 2006 2x4 Commando 650.

This past weekend I noticed a clunking type noise coming from the rear diff when turning sharp and more so when backing up in a turn. There does seem to be some side play. It is full of fluid. What should I look for before hunting season gets me stranded.

Are you driving around with your locker on all the time? This is especially tough in your machine if it's on pavement. Does it clunk when the locker is disengaged? How many miles on you machine? Can you tell how play? 1/8 th of a turn? Some play is normal.

Correct, Commando always locked. I do drive on pavement some from cabin to the BLM  land but take it very easy when turning. I will drain fluid and check the Diff fluid for metal. I completely forgot about the CV jt could be the culprit and a WHOLE lot cheaper if they are available for my machine.

2x4 Commando 2006, 650cc.  with maual dump bed.

Looks like my LR CV is dry. I've pulled these CV's out of the Class 1 cars we ran so should be about the same principal with these I think. If any one has a you tube vid on pulling CV out and rebuilding that would be awesome. There still feels like a 1/2" of play maybe in the dif gears. Is that to much. Are the rear CV's available?

      Bought a used 4x4, engine runs. Tried rebuilding both pulleys. Ended up buying a transmission pulley system. The new one is aftermarket. The old one wallowed out and fell off.
      The new one seems not to have enough splines inside. Seems like it is freewheeling. When it revs up and gets smaller pulley diameter, does it jump on the spline shaft? The driver pulley on the engine gets larger when it revs up. Had to make a pvc collar for the belt to sit on in the grove. No parts for sale on this pulley. Is the belt supposed to sit at the bottom? There must be a trick to get the belt on. Any ideas?
      Thanks Dave in Florida

      I have a 2022 Hisun 750 Sector which comes with a locked rear differential. Was wondering if it would be possible to install an unlocking differential.  I see that there are some Hisun made machines that come with the unlocking rear diff, such as Cub Cadet Challenger, some of the Massimos, and probably others. My concern is whether these would be a direct bolt on, using the original axles, drive shaft, and of course matching gear ratio. I've tried to match up part numbers but it seems every brand has their own number system even for parts that I know are identical. If anyone has ever done this swap or has any information about the whether these unlocking rear diffs are comparable to the Sector, I'd appreciate your input.
