    '96 cheyenne 14bolt,9.5", SF, 8 lug, parts problems?

    after putting new c-cips in and old cross pin, it eliminated the in/out play of axle on one side and lessened the play on the other...im going to have to do a re-evaluation...i dont think the vibration is coming from differential. I may have to do the "under the truck camera" to find it. Im...

    my bad...i didnt see the length measurements on the site, thanks for pointing that out. I think you are correct. My pin is 142.25mm. 144.78 is much closer than 148

    '96 cheyenne 14bolt,9.5", SF, 8 lug, parts problems?

    what a journey...as some of you know my situation, Im going to a new thread concerning how to find the correct parts. I had issues with this truck as described in the threads, "is ACDelco 10-4051 gear oil discontinued", and "Thump thump G80 and confusing gear oil"....so I decided to replace the...

    is ACDelco 10-4051 gear oil discontinued?

    if you are driving the truck, Id at least pull the fill plug and see if there is enough oil in it...mine only had less than a quart

    Thump thump, G80 and confusing gear oil

    I just found some info about adding weights to drums, is that a sign of a mistake? The side im having problems with is where this drum with the weight was, not saying that it contributes to the problem. If it were you would you replace drums? Im also thinking the wheel bearing play could be a...

    Thump thump, G80 and confusing gear oil

    thanks Schurkey, but can you explain the welded piece on wheel drum? it doesnt appear to be from the factory

    Thump thump, G80 and confusing gear oil

    something im now wondering about before I have drums turned is this piece of metal welded to the outside of the drum, im guessing to balance? I really havent given it much thought until now. Also, I noticed that I have a bit of side to side/ up and down play in wheel bearings

    Thump thump, G80 and confusing gear oil

    The drivers side is not engaging, feels that is where the binding is...if I get in wet grass and give it the throttle, the right side wheel spins, never the left. I dont understand about the clutches or how they work. Could clutches bind on just one side?

    Thump thump, G80 and confusing gear oil

    since the mechanics i know are 2 wks or so booked up, I decided to give it another look. I dont see anything wrong, everything looks good. I dont suppose that a person can start the truck, put it in drive, and see whats going on with the diff cover, wheels, and drums off. I can spin it around...

    Thump thump, G80 and confusing gear oil

    thank you for that info, im new at differentials apparently. Ive got it on the stands now and when turning the axles i can tell theres something not right inside there. Im getting ready to pull the cover again but this time im going to look much harder. I was ignorant the first time by thinking...

    Thump thump, G80 and confusing gear oil

    as i mentioned before, while on jack stands the passenger side turns but not the drivers side, I even got it up to 60mph and never any movement from drivers side, so locker must not be working for some reason.

    Thump thump, G80 and confusing gear oil

    brakes dry, cleaned the dust, looks like they were changed a few miles back...best I can tell, look good. I did notice that they are the bonded brakes, but im beginning to think it is not the brakes

    Thump thump, G80 and confusing gear oil

    brake drum not hot...looks like rear diff problem?

    Thump thump, G80 and confusing gear oil

    I celebrated too soon, back to the drawing board. I drove the truck around 15 miles, no issues except for pulsating braking....then it started to feel like a brake was grabbing. It felt like I was dragging a tree, with some noise something bogging it down. The problem is in the rear drivers...

    Thump thump, G80 and confusing gear oil

    Success! went on big test drive, no thump. Differentials work better with oil in them. I have a bit of brake pulsating/slight grabbing at times seemingly from the rear which will be another project along with a good grease job and probably a transmission fluid change, but Im psyched that I have...

    Thump thump, G80 and confusing gear oil

    after cleaning her up, painting the cover, gasket with ultra black, and filling with oil, went for a small test drive...yippee...so far, so good, no thumping sounds. I just got it tagged and insured, so now for the big test drive. Thanks to everyone's help.

    after much reading I finally decided to use the Valvoline 80W/90.

    Thump thump, G80 and confusing gear oil

    thanks...first thing i did was remove the fill plug, thanks to you guys on this forum. I dont see anything blued, i have a gasket and some ultra black permatex. I hope bearings/seals are ok, but at least this is a start. I just have to wonder if the diff was filled with an oil with LS additive...

    Thump thump, G80 and confusing gear oil

    hopefully im making progress...im ready to pull diff cover off, noticed where some gear oil had leaked. cracked cover apart and I would estimate it only had around half a quart fluid. I was surprised that everything looked very good according to all the info ive seen, no broken parts, little...
