what is a good price to pay to get a 3.73 gear and posi put in my truck? a good place to order the parts or get it done local?

 

About 180-200 for gears and 300-350 for the posi unit. These guys have very good prices and excellent service.

what about installation for just posi?

 

Tokez, whatever you do...call several places and compare prices first.
I bought the Eaton posi, Precision gears and master overhaul kit from an ebay store for $560. It was a place in NY. Once I got the parts, I started shopping for the install place.

I went to 4WheelParts first because I knew they were big/well known and did good work. Well, with hugeness comes a price. They wanted $550 for JUST THE INSTALL and the Eaton, gears, install kit and fluids for like $900.
I was glad I bought the Eaton and gears online, I about **** my pants when the guy quoted me $1400 total
So I just look at the guy in astonishment and tell him..."Yea, I'll give ya a call next week" before I leave
YEA RIGHT!

Called drivetraindirect.com in Corona. Some guy I talked to said they'd do the install for $280 (if I remember correctly).
I was like cool, I'll set up an appointment tomorrow....call the next day and I talk to the manager...he says, "I don't know who you talked to but we don't do just install, you have to buy the stuff from us too."
So I'm like ****, had I bought the stuff from them, which, might I add, was cheaper than the place I bought in NY from, it would've been $780 total ( I remember that much because I was pissed over $20...yea..I'm always searching for a better deal ).

Me = $560+$40(shipping)=$600+$200(install)=$800.

So since I couldn't go to drivetraindirect.com they referred me to Hooper's in the good ol' San Fernando Valley. They did good, fast work and I don't know if you saw the video I made of me and MacADaYear doing donuts, but it's so easy to spin the tires now, not to mention the gears kick ***...
The flat rate for rear end work is $200 at Hooper's. Meaning if you have just the gears installed, its $200, or just an Eaton...$200, or both (like me) $200. Just do both at the same time and save some money on the labor

 

try looking in a junkyard for a nbs with the 3.73 [psi alreadu in it and buy the whole axle codes in glove box need to be
3.73 = GT4, GQ1
G80 = Locking rear differential
if those codes are on that little white sticker in the glove box tada you found one!

 

yea i cant decide what to do.
at 1st i wanted the 4.10 eaton combo. but since when hodgeee posted about blowing his drive shaft im thinking twice. and i drive to the bay area and TJ alot. so i think gas milage would kill me. im thinking of leaving the 3.73 on. and getting just the G80 since they're so cheap. the only reason i want the locker is because even tho i dont go off roading, when i do, i always get stuck.

 

Yeah, around $200 to $250 for rear end work is the norm, an a good price.

If you're only looking for improved offroad performance, look into lockright lockers. They replace your spider gears, cost less than $300, plus you can install them yourself if you are mechanically competent with basic tools. You don't have to reset the gears, or replace the carrier if you have an open diff.

Now for the negatives. It's a bit harsh on the road (much worse than auburn or eaton), because it's a full blown locker. Plus they are not quite as strong as an eaton or auburn, and are generally not rebuildable. I've run them for years in my jeeps without much problem at all, but then I don't mind the tire chirping and harsh characteristics of a locker.

Just food for thought

 

so what parts should i look for in order to make my rear end a posi? sorry for the stupid question but ive never really missed with a truck rear end
