Question Gearing up!

Anyone know where the best place is to get rear end parts? I've got 4.10s now but I want to go to 3.73s or 3.55s for my 97 F350 psd dually.

I just did a web check for gears. Most places are charging between 200 & 250. I paid 236, incl tax, at a Ford Dealership for my 4.10's. Are you going to change them yourself? If so, I hope you have the right tools for setting up the pinion depth. Ford shows a special tool for that.

Randy's Ring & Pinion http://www.ringpinion.com/. Good guys over there. If you've never done it before, ask them for complete instructions and follow them to a T! It's real easy to burn up a set of gears if the setup isn't just right...

There are several manufacturers, check out dirt track racing mags. On doing the swap, I'd give it to a professional. I've done several for a race car, which we didn't worry too much about. Then did one on a daily driver and it was a pain, a lot of assembly, check it , dis-assembly,add the spacers, re-assemble, check it again, cuss for 3.5 minutes, dis-assemble, etc! Even though I consider myself a good shade tree mech, I'd take any future jobs like this to a pro for a daily driver, especially my beloved PSD.

I just got a set of second hand 355's for $20..... New gears here are around $500 CDN, add another 400-600 for install and it's just out of reach for me at the moment..... I'm shopping for the tools instead.

When I did the daily driver swap, we got the install kit with a video. It helps, but the crucial check is to put some goo on the gears, turn the assembly and look at the pattern that is left. Checking the pattern was the only subjective part of it and that is why I would have a seasoned pro check it. Not to mention the right tools to remove the bearings if it was not correct.

Wouldn't ya just love to spend a few moments with the engineer that decided that the shims go behind the bearings? It sure makes you appreciate the Ford 9", nice design.....
