Anyone do there own rear gears?

[OrangeMustangGt]

I NEED to switch gears, as my 3:73's are not good for boost at all.

Now, I KNOW i could do it, but ive never done it.....I had my last gears installed and it cost me about $300.....needless to say, ive taken apart just about everything on my car without a problem, so i know i can handle some rear gears!

My only issue is setting up the rear end with the correct lash, ect, and was wondering if there is any websites giving a detailed how-to.

By the way, anyone want to trade some 3:73's for say 3:27's?

thanks guys

Also see Scott's (Mo Dingo's) self-authored write up (in his sig). He did a real nice one as I recall.

Good luck.

I do all my own work on my car...EXCEPT FOR REAR AXLE WORK.

Nothing is more miserable then playing in differential fluid while laying on your back under your car.

I'll gladly pay someone for work like this.

I'll second that! I did one on jackstands years ago. Never again! Installing gears while on your back sucks. It takes about 3 times as long to do and trying to hold the diff in and get everything bolted up then setting backlash,while on your back, feels like your upside down.Its just a nightmare. If you had acsess to a lift then I would say go for it. BTW I just paid $200 for complete install on a new eaton posi, gears,axles,seals,bearings....ect.

I'm doing my own gears in a few hours. I'll let you know. Of course I have help from someone who's done it before. I have my rear pulled out. Im doing all new bearings, seals, axles, carrier and 4.30 gears.

I wouldn't attempt it as a rookie by myself.

I hear you loud and clear 95vert354...over the winter I removed and rebuilt my traction-lok. What a miserable mess.

See my gears link in my sig. Read each install article that I have in my writeup several times over until you understand. The article that says I have some pics and info if you have some specific questions, like setting up the dial indicator.

This link proved to be the most helpful in taking the info I had from the install articles, and putting them into my mind with his pictures. It really helped.

Backlash (maximum distance between a pinion gear tooth and an adjacent ring gear tooth) is set by the carrier shims, which are 2 huge shims from the factory. If you buy FMS gears, you should not have to even change them. My backlash was within spec with the stock carrier shims, but definately check it anyway. You never know.

The pinion depth (distance from the center of the ring gear to the top of the pinion gear) is set by the total thickness of the pinion shims. A pinion depth gauge is expensive, and with FMS gears you don't need to use one. All this is covered in my writeup, so I won't repeat it again.

If you have any questions, just PM me.

if you want to drive to fl i'd be glad to swap rear ends with ya, then you don't have to worry about the lash and setting them up

I have done mine several times. I purchased a micrometer to measure the old pinion with the shims and I match the measurements with the new one. I use a cheapo dial indicator with a magnetic base to set my backlash.

I have installed gears 3 times now and no problems yet.

That link to Corral.net is a good one.

The most important thing to keep in mind is this IMHO

The gears need to be setup correctly

OR

They'll howl like a Banshee

OR

They may even be damaged

IF you think you can set them up verified by the NECESSARY tools.

Go For It

I have some 3.27's gears from a 02GT with less than 10K on them. Don't really need 3.73's...let me know if you want to work a deal (in NH).
