AMC 20 problems

My problem is that on last mon I was driving and heard BANG Well in the diff the spider gears are held in plase with the cross shaft. That cross shaft has 2 C-clips. one is not on there any more.
#1 question. where can I find just those C-clips?? Can it be just any C-clip or are they special I can't upgrade from the trash lock right now and WILL NOT pay 150 for new trash lock gears.
#2 question is having the rear up and rotating the tires (both going the same way) the tire moves freely about 1/2 to 3/4 of the way around and then the rear binds up to the point of almost having to force the tires to get them to turn :teary: why would it do that?? also on the pinion gear there is one part of a tooth that broak off. the rest of the gear teeth look ok. I THINK I'm just trying to get an Idea on what I should look at doing.

If the main bearings were tightened down and not all torqued to the same amount would that cause it to bind only in a certian spot??
Any help is appriciated TIA

Re: AMC 20 problems

out of the few amc20s ive torn apart, Ive never seen one with c clips on the center pin?

all the ones ive had had a single roll pin holding that center pin in place.

from teh broken pinion gear, depending on what portion is broken, you MIGHT be able to limp it along, or you might need a complete gear set, and re set up done.

Id take it to someone with the knowledge and tools to set up ring and pinion gears, and get an estimate.

Re: AMC 20 problems

Ozark is right, there are no c-clips on the AMC 20. The axle is retained by the bearing retainer plate on the end of the tube. Why not get an open carrier and later, a lockright.

Re: AMC 20 problems

The binding is probably that chipped tooth in the bearing, doesn't sound good. There should be no binding anywhere.

You sure you have an AMC 20? They never had C-clips, as others have mentioned.

Re: AMC 20 problems

yep I have an AMC 20. I never thought they had c-clips either but if you look in any of the cataloges you will see what looks to be 2 c-clips in the track lock spider gears.

Re: AMC 20 problems

Will, the c-clip is not holding the axle in. The c clip holds the cross shaft in position inside the diff, without the clips the cross shaft can move out and contact the side gears, that was the other noise I heard.

Re: AMC 20 problems

Sounds to me you have bearing problems and other problems. I dont have a pic of the trac loc put if you say there is a clip missing then the pinion must have picked it up and broke the tooth off then the pieces of the tooth and that clip are now in your bearings and you have a bad bearing and that is the bind you feel. Its time for a rebuild. You may be able to jury rig it, but how, when, and where will it let go totally.

Re: AMC 20 problems

I think a rebuild is inorder too, but the wife is gonna kill me. If the R&P was not installed correctly that would have caused this?

Out of curiosity what is an average for a R&P and ARB install??? I'm just trying to get some ideas. I know in diferent areas the cost is diferent

Re: AMC 20 problems

At work we get 250 to 350 for a install setup. With an arb it will be more because of all the air line work.

You keep asking question about different things. What all has been done with this rear. It sounds like you just setup the gears and you think you did them wrong. Give us the whole story it may help figure out what is wrong.
