Chevrolet S10 Differential

[Blankenberge]

I can't find nowhere in my manual the clearance between Axle Shaft and Pinion Shaft in the Differential of Chevrolet S10 1996 4Cyl 2WD

If I understand your terms, the axle shaft does not meet the pinion gear in the diff. unless you mean something else.

I'm as perplexed as Max is. Not real sure what you are after...the axle shafts go part way through the carrier assembly and are stopped by the pin that runs through it, then held in place with "c" retainers. The pinion is at the front of the differential and has the flange that the prop shaft (drive shaft) u-joint bolts to. Axle shafts do not contact or come near the pinion gear.

explain what your up to /doing with this diff. my guess is this is an open diff. not all that complicated.

replacing the pinion bearing ?

Maxwedge; In my GM Service Manual for S/T Truck they call that small shaft, with diamater 19mm/3/4inch and a lenght of 112mm/ 4 3/8inch and secured with a small bolt "the pinion shaft" . The shaft You mentioned they call" Pinion and Ring Gear Set".So there was a misunderstanding between us.What I want to know is the clearance between the Axle Shaft and that small shaft witch is secured with a small bolt.Sorry to bother You with my problem

I think you are referring to the central pin that runs through the differential case, supporting the spyder gears between the side gears. GM refers to this pin as a pinion shaft also. Since the axle shafts float in and out somewhat due to wheel bearing play I'm not sure what you're after. With the axles pushed in they shouldn't touch.

the ring gear and pinion gear are matched. this means you must replace both and they must be a matched pair. the backlash measurements and the wear pattern is used to determine how to shim the diff.

this is a work that I would not do if you have no experience in this . this requires special equipment and knowledge .

you still did not explain what/why your asking these questions.

what did you replace ? why did you get to this issue ?

Okay. I think what you are after is the rear axle shaft end play specs, and I'm not aware there is any specific spec for that. The "pinion shaft" and the "c" retainer keep the axle in place. I've rebuilt several of these rear diff's and don't recall any such spec.

Like J cat is asking, what is the problem with the rear end?

Sir, I'm living in Belgium( Europe) and every Year we have to go to the "Automobile Inspection" Last time(octobre) they put a warning on my Inspection Form. there was to mutch axial clearance(end play) on the rear wheels.Just suppose that the end play is 1/32 inch/0.75mm so when I'm driving my car the rear wheels are moving in and out,in and out(rear wheel bearings are roller bearings not ball bearings)witch is not normal, so there must be a specification about that axle end play.I think the axle endplay must be in the region of 0.005 to 0.009inch or 0.13 to 0.23mm and can be adjusted by thicker "C"locks witch I will make myself on the lathe Probably its the only Chevy S10 riding around in Belgium.I also had a remark on the Front Brake Discs, the surface looks terrible, but that's another story. Thanks allready.

With thicker "C" clips you'll have to machine the axle grooves too. Not a good idea. Radial and axial play will increase with bearing wear. You should have asked him what he thought the tolerences were. Thats the criteria you'll have to meet.

[gmtech1]

DeltaP brings up a good point. What specs are the inspectors using? Some end play on these axles is normal...

Thanks already.

the axle end play of about 1/32 is normal. you must have some movement on these. perhaps if your driving at 200 MPH this may be a factor.

this is another post from EU that I have had ask very weird questions concerning GM vehicle.

last time is was what is the max speed of the vehicle ? would not allow operation in EU until this was with offical documents !

The fact is that when they see an American Car is to be inspected theire attitude changes espescialy when it is on LPG,like most American Cars overhere.They want to find something .Like the rearwheel test on my car,they put the wheels on moving plates and they watch and listen,so when there is some clearance they hear(stetoscoop) something like "Cling - Clong" they decide there is something wrong with the bearings. Probably they never heard about "C" locks and no way talking to them.Thanks for Your intrest and Happy Holidays we will wait and see
