Rebuilding rear end

To be perfectly honest with you guys, if you have no experience with rearends, you're much better off taking it to somebody who does. I rebuilt my rearend myself because I couldn't afford to have somebody else do it. The result was an extremely noisy truck. the rearend never failed, but the humming continued getting worse until I finally had the money to regear the truck and I paid somebody else to do it. No more noise. I followed the directions exactly and had everything within tolerances (as far as I could tell) and it still was not set up correctly. You have to remember that you're dealing with thousandths of an inch. If you are off by even just a couple thousandths, you could end up with anything from a noisy rearend to a grenade under the truck. Not to mention, you need a pretty large list of tools to complete the job, including a bearing press.

i agree, i have done many ring and pinions on many difrent vehicles, it is a very time consuming process. you will need some expensive tools(magnetic base dial indicator, bearing press or arbor press, micromiter) not to mention alot of other tools(some times a case spreader is needed makes it easer) getting your pinion depth and your backlash set up correctly you will be pulling the carrier and pinion out and putting them back in many times to get the contact pattern perfect and the baclash within specs, if you are a decent machanic take your time and dont get frustrated, one time it took me ten hours to do a ring and pinion other times it lined right up first try and only took 2 hours, here are some tricks to make install go easer
take off all the old bearings very carefully off the old carrier and pinion, grind off the inside race of the old bearings so they will slide easely on the new carier and pinion, use these as set up bearing so you wont damage the new bearings pulling them on and off to change shim thickness
mesure the curent shim thickness used on the old pinion and carrier and use this as a starting piont to find the new thickness you will need, most times it is very close to the new thickness needed
reuse the old crush sleeve and pinion seal untill you have everything within specs only on final install use the new crush sleeve and seal.
good luck

I agree: this is not a DIY process.

Do you really need to pry out the carrier, I have rebuilt a couple of chevy and dodge axles, and the carrier just slid right out, and back in again. Then again, I have never touched the Ford 8.8. I was about to buy a set of 4.10s to replace my 3.55s, but how much of a pain is it to do these 8.8 axles?
