i got used FRPP 3.73s, did the install going in blind having never done it before, used the old crush sleeve

USED THE OLD SLEEVE!!!!!! WHY??? they are cheap.. you can get away with not measuring but thats extreme

what? you dont think i did my gear install myself and did it fine without knowing how right off the bat? if you have 1/2 a brain you can pay attention to what you're doing and get it done fairly easily..i dont see why people make such a huge deal out of doing it...if 1/2 the people who say its so hard actually tried it themselves they'd realize it isnt all the make it up to be

It just seems unlikely especially since you claim to have reused the crush sleeve...

Please stay on-topic and nix the personal jabs in this Tech thread.

anybody can do gears as long as you are patient. backlash is a mechanical number. you use a dial indicator and you shim till it is correct. if it is not correct it is not correct.

the wear pattern is the same way if it is wrong it is wrong.

preload you only need an inch pound torque wrench to verify that. you need x-amount of rotating torque to achive preload.

now that being said if you don't have patience and want it now pay somebody. I have 3 cars so why pay someone more than I make to do something that requires time.

I would not re-use a crush sleave. they are not expensive there is no point IMO.

the main thing is read, read, read before you tackle it. Anybody who will tell you not to do it is proably just kind of afraid to work on things. On the flip side this is not the kind of job you can just hack together. If things are wrong you will get noise or premature failure bottom line.

I have come to think in the new generation people are just aftraid to work on cars a bit. if it is not a CAI or underdrive pullies someone will chime in how you can't do it yourslef which is just BS.

I had to use a press for my install for the crush sleeve I believe.

why did you need a press for your crush sleeve?

Kilgore Trout · Feb 21, 2006

You tighten the pinion nut until the crush sleeve deforms. When you hit the target preload you stop tightening the pinion nut.

Did you have a magnetic base dial indicator for the backlash as well???

I don't think NASA has a "magnetic base dial indicator"

Sorry lol...sounded so techniqal

Mike97gt · Feb 21, 2006

he probally reused the sleeve because he did not know better. to be honest many many of you guys that have gears installed by other probally have unmeasured gears. 99 percent of techs reuse the old shims.

justin. next time you do gear get some new crush slevees

I'm hoping you torqued those axel fitting nuts back on to their proper setting? I'm hoping you did anyway or you might be having some problems down the road.

Justin03GT · Feb 21, 2006

i re-used the crush sleave under advice from a guy who has been building cars for more years than i have been alive- my grandfather...he has built and restored probably 50 mustangs since he started working on cars and i trust his advice...i did use an in/lb torque wrench to set the pre-load and thats it...like hognutz said, patience is key and dont be afraid to do some work... the gears have been in for almost 12k miles and all of those miles i have been spraying n20 as well, they still don't whine and removed the differential cover last week to clean it up and fix the slow drip leak i had from it and everything look good inside, the gear oil wasnt ugly and there wasnt any metal shavings anywhere, so i'd be willing to bet everything is fine.

hognutz · Feb 21, 2006

The only down side of re-suing a crush sleave would just be if the preload were to change because the crush sleave was used. If it does not you will be fine plain and simple.%2

soon i'll be doing a gear, bearing, and LSD swap i'll try and take as many pics as i can and do a thread on it

Great news, the existing gear installs out there are pretty weak...

yeah there are some issues I rean into.

1. getting the abs rings off for an axle swap.

2. the ford carrier shims are a bit different than I am used to. thick cast iron and expensive.

3. no pinion depth on the ring and pinion for some reason.

I think I may post a bit of a redneck/poormans tutorial on some of this stuff when I finish up. there is not that good of advice about some of it. there are some little tricks you learn that make it go fast. People will tell you have to use a press or puller sometimes when it is just not needed. Like I was told it was hard to get the abs rings on becasue they break or you need a press to do it. funny how two blocks of wood, a rubber mallet and something to craddle the ring (bearing slippter in my case) worked perfect. Now I am sure the wrong approach would have jacked up the gears though.

The first one has no pics, the second one is too confusing, I did not look at the third one too close but my initial assessment is that it is pretty good

Where can i get a dial indicator and what could i use instead?

3:73 Install??
