how might i go about changing the gear ratio in a 2001 ram 1500 RWD, it's 3.55, i am thinkin about a little higher... don't know about 4.10... how might i go about it? if i have to i will take it to the dealer. but is it possible to do it myself?

 

its possible to do it yourself if you have done rearends before or know somebody that has, you have to be careful about shims. i probably wouldnt go to a 4.10 im personally looking at upgrading to a 3.92 for my 2wd. im sure others will chime in shortly

 

i pretty much just want 3.92... if i have to go to the dealer whats the average labour time?

 

i imagine the dealer would hit you pretty hard. probably around 1500-2000 is my guess. I used to build swamp buggy jeeps so i know how to change gears. they are a pain to do it right but if you do it wrong your in for some money

 

you have to set the lash right?

also i have 4.10's and running 265/75/16 10 ply tires, and its a perfect combo IMO....

 

yeah you have to set the lash, any grinding is bad news right off the bat

 

how do you set the lash? what tools are needed? if you dont mind informing me



sorry to OP, I'm not trying to jack the thread

 

The dealership will rape you. Don't go to them, you can get just a good of job done by a quality mechanic that you trust. Make sure they are good and you trust them, because there are a lot $tealerships and mechanics out there that will screw the job up.

For labor, you're talking $300-$400 for the rear axle usually.

 

i paid someone to do mine 800 for parts and labor. i got the mopar lsd.

 

A friend of mine just put new gears and a posi in his camero, he had some help from his dad but he said it wasn't all that hard. Just need to take your time and do everything correct and not skip any details.
