Ok a month or so ago My rear tire/s were draging on turns intermitantly. I parked it.Once or twice after it cooled down I took it for short runs into town and nothing happened. But I want to take a look and be sure before I cause more damage.Tomorrow I will be taking the cover off and looking for obvious damage. I have a posi unit of some sort is there anything special I should look for ot measure or test?

What fluid do I need to put back in. What about the posi additive?
Thanks for the help.

 

most people complain when there posi doesn't lock. And they look for clutch material. I guess if its staying locked. Just look for broken stuff

 

can i use some sort of degreaser I can use in there like brake cleaner

 

Do not use brake cleaner in thier unless you would like to have your rear end jerk around the corners for a while till the oil gets worked into the clutches agin. A cheap easy thing to try is to get a bottle of additive from Chrysler and put in the rear end drive it around town for a while and see if it goes away the bottle is only $6, and if you decied todrain and refill be shure to put a bottle in or it will grab and try to lock all the time.

Refill it with a quality 75w90 Hypoid gear oil. If you tow frequently go for a 75w140 synthetic gear oil. Check the new oil bottle because some gear oils already have the "posi additive' or friction modifier in them. If not buy a small bottle of friction modifier and add it first. Then fill with fresh oil.

When you're all done do some slow tight figure 8's in a parking lot to help pump the new oil into the clutches.

Good luck

 

Great news! Not really. I opened the cover and all sorts of tinny chunks of material were all over everything. I guess the clutch packs broke loose. Can I let it go as is and still drive? Is there a cheap fix for this?
