rear end clunking.

sounds like a plan but if i may did the factory some 50 years ago have to that.

Well, from my limited time in a dealership, if we had a complaint of rear end "clunking" on something relatively new with a Sure Grip differential it was suction the old lube out, refill it, add a bottle of "magic sauce" and do the figure-8 routine in the used car lot. Never had it fail. Now I'm not saying you don't have another problem but that's where to start.

Well guys we got some nice temps so went for a drive and did the figure 8 thing clunk clunk like crazy. but after a few more miles it got better, and grab Cindy and went for a drive and quit now. hope it fix itself O i did add 1 1/2 sure-grip additive now it looks like booth new wheel cylinders are leaking.o well more fun thanks again gents.

I allways have a hard time pouring fluid in a diff, so i was thinking pour it in the vent hole, should work .

I pour it down the axle tube before I put the axle in !
