It this something that can be done at home? I was quoted 500 + to have a mechanic install gears. I did not think it would be that tough....
What special tools are needed if any.
Thanks,
Jeff

Im looking at my receipt for the 4:10 gear install...
Labor 4 hours @ $80 = $320
Fluids = $14.50
Hope this helps.. that labor rate is California and about standard.
I would recommend it being done by a professional. Not all gears are exactly alike. Sometimes shims are required and unless you plan on spending a lot of money for shims, pay to have it done.
Here is another question....
Lets say you are traveling at 70 mph. What RPM would you be at with the diff gears... 410's 430's etc...
My 4.10 install cost $600.00 hmmm... I was not happy
With the 4.10 in the speedo is off by about 16%.
My speedo read 50mph and "the your speed is" electric sign on the side of the road read 42mph.
And no, I would not recommend doing it yourself.

I realize the seedo will be off until the car is chipped.
What I am accually looking for it the rpm's when traveling at 70mph with corected speedo's.
Thanks for your input :-)
I done it before on a 1980 Ford Bronco, you need calipers, blue ink to test gear mesh and contact, if you get the backlash wrong you will get sounds you won't like, not enough backlash you will have premature and uneven gear wear. Removing and reinstalling is easy, Getting the backlash to specs...can be a pain.

If you haven't done it before have it done on your new $$ car.
If was a second car or hot rod hobby car, do it yourself to learn.

It is kinda my second car and I am thinking the way you are. I want to learn what I can. I just dont want to get in there and not be able to do it at all and have to tow it....
I did do the front shocks Everyone told me to stay away from that too but it turned out to be pretty easy.
the $500.00 thing scares me into thinking its harder than I thought it would be though....
You can do it, if you get stumped along the line you'll have to find a rear end guy in the area to help, most of us mech guys will help out and are good guys, one may even take the time to come over to the house if need be, I've done it before for people.Originally Posted by jettle
