i was wondering if anyone here has done them themselves? i plan on doing it and i work at a shop where i can have the hardcore mechanics help me. i jsut wanted to know if anyone has any useful hint or anything that can help me. thanks

 

did you buy them yet? if so what kind are they? motive? FRPP? If not, try to get the FRPP ones, actually made by FRPP, they go in easier with less whine so I've heard, hopefully some of the mechanics there have this before, helps to have experience with these things.

 

i havent gotten them yet. im ordering them next week and i was gonna tackle it next weekend. i was looking at the motives just because they are cheaper and im on a budget with having to pay out my *** for the car and going to tech school. the whine wouldnt bother me since my exhaust rattles and theres a leak in my header that i gotta fix haha

 

I def wouldn't recommend it unless someone in your shop has the experience in installing gears... it is not an easy thing to do and there is a lot of room for error... your backlash can't be remotely off what so ever... if you're adamant in doing it anyway then I wish you the best of luck. Tell us your thoughts afterwards ~ J

 

Unless you have done this before on a 8.8, i would have someone else do it......you can thank yourself later for the saved headaches. FRPP or go home too!

 

i mean ill ask them but theyve been mechanics for 30 or so years so i wouldnt imagine theyve never done it. or even a few people at school might even know. but insist on doing everything myself because i hate paying people to do work on my car. the clutch and cams are going to be fun haha

 

Motives are fine if you know what you're doing. I have zero whine. But if there is someone there to help out more power to you and good luck. Make sure to have a bearing installed kit and when I did mine I set the clutch packs tight to get rid of the noise even though Ford says to make them loose.

 

FRPP --FTW

 

Me and a friend installed my frpp 3.73 gears. 8.8 rear axles set up like a 10 or 12 bolt chevy. If someone there has done one of these they should be able to help you. An excellent starting point is to pull bearing off of the pinion and take off the factory shim. Put the factory shim on the new pinion and press on the new bearing. I used factory shims on the pinion and the carrier. I ended up with .011 backlash and aperfect pattern,no whine here. Also make sure you get the preload on the bearing correct when crushing the new crush sleeve. Pinion depth and bearing preload are critical on these rearends,if correct,no whine.

 

+1000 on having a pro do it. I work at a Dealership, and I sent it to a rear end shop.
