I am looking to put a 4.10 in my truck, and dont mind doing so myself, if I feel confident enough for the job.

Other than the r&p, and full rebuild kit, what else do I need-as far as tools go?

Do these use shims or a crush sleeve? Or is this a job that I should pay to do?

 

shims, If you have never dun one before i would say pay to have it dun........unless you have a buddy that has dun one before that will help. that was sexselffull

 

dunno what axles are under the 1sr gens, but, danas use shims on the carrier (inside the bearing) to set ur backlashh and preload. the pinion will use a crush sleeve. shims and the sleeve will be included in a master install kit. to get the backlash set, i took the old carrier bearings and ground out the inside so they slip on and off, then get ur backlash figured, THEN press on ur new bearings.

ur gonna need a GOOD impact to get the pinion nut on and off, a way tomeasure ur backlash, a good press and a bearing splitter. i hhad the hardest time getting the bearings off the carrier but i only had a press.

take ur time and get a good pattern, set em up tight and give it a ultra meticulous break in. good luck

 

Useing one set of bearings as a set up tool and assembling with a different set is Not a good Idea. The width variation between bearings (cup and cone) can be .020 so what one bearing gives you another may not.
If you are not planing on changing carrier bearings the preload of the carrier has already been determined for you. All you will have to do is move shims from one side (its about .001 lash=.001 shim change) to the other to set your backlash.
The pinion is another story though first you have to set your preload (20 in/lbs w/out seal - new bearings) then set your depth. Unless you have the depth tool this will have to be done by trial and error. Each tme you move the pinion you will have to reset the lash.

 

its always worked to get it close for me, so u at least have a good starting point....i can def see where there'd be some variation, but its served me well to find "the zone"

 

I've had a center section and rebuild kit sitting on one of my workbenches for six months now waiting for me to get up the nerve to dig into it. I have all the tools and plenty of mechanical experience, just never did a gear setup before. Guess it is just like anything else. Make the call and dive in. You'll figure it out..

 

You don't just slap the new bearings in where the set-up bearings were -- you measure the thickness of the set-up bearings vs. the new bearings, and adjust the shims accordingly . . . you just need a decent set of calipers. Measure the thickness of the set-up bearings, slide them on the carrier with no shims, put feeler guages on each side until she is in the right place, then measure the thickness of the new bearings, add or subtract as neccesary to the feeler guages you used, add .002 to each side (to get your .004 pre-load for new bearings), and put her together. With a little luck, you will be right on.

The pinions are harder, but have numbers engraved in the end that tell you what depth adjustment from "0" they require. The manual has a section on this. If you adjust for the difference between the numbers on your original pinion, and the numbers on your new pinion, you should be able to adjust the pinion shims without trial and error, too.

It can be a hard job, don't get me wrong. I still have a limited slip unit sitting in my garage waiting to go in.

Just take it easy, and hope you are lucky. If you aren't lucky, stay calm, take it apart, and do it again. You can definitely pay for a good OTC bearing seperator by doing it yourself!
