cost for getting 3.73's ?

[merc91]

i have a 91 merc with open 2.73's and i'm looking to get open 3.73's. What do you think it would cost about for the parts, and then the labour? I don't have the gears or any parts by the way. and i'm going to buy all new also.

thanks andy

I think it cost me about $1K to have ford do it for me

new trac lock, new 3.73 gears, new bearings and seals, gear oil, and labor runs around 900 bucks with me

I also recommend getting an aluminum driveshaft while you are at it.

I had Scottmang do 3.73s and a trac lok in mine. He is the man. The gears were used, but I had bought a new trac lok unit. Very happy with the results.

I did not get an aluminum driveshaft (although I thought I'd need it). I have had no issus with vibration, although numerous others have.

It really costs that much for parts and labor for a gear install? Holy crap. I made a 70 dollar profit putting mine in.

Doing it correctly takes hours to do, especially if you are a n00b. I have seen that a lot goes into aligning everything properly. It is really essential to get it correct.

I know doing it correctly an take hours to do sometimes, just never had to pay anyone to do it for me. I know a lot about shimming gears. After doing a volvo penta drive, a car axle is cake.

id love to put some gears in my car but about $400 for the install plus another $300 into the gears just isnt do-able right now. might get into it over the summer. rear gears just isnt my thing

i was the 8.8 was set up like the 8'' and 9'' where the center section just unbolts off the housing and i could just swap the pumpkins

[merc91]

hmm thanks, haha. student wage won't let me get that till the end of summerish... but looks like i'll be set back 700 bucks or so in the end if i go with the open rear for now... better to get a good job done on open rear then cheep job on posi i guess, haha.

thanks guys, andy

Labor is free if you do it at home ...

I would not suggest doing a 3.73 open rear. It will wheelspin like a mofo, unless of course thats your goal If you're worried about snow manners, I find that panthers with a traction lock behave much better than open rear cars, and aren't as easy to get stuck. My Mark VII is absolutely awful, 3.27 open rear.

trust me, I want 3.73 trac lock baddd.

but i'm 17, and in Canada so double $$$ for anything it seems... and every penny i make goes into this car, and has to stretch a long ways (but doing things rite), and all those pennys will only get me 3.73 open. and with 275/60/15's going in a month, i would much prefer that rear end vs my 2.73 open. still will take me until august to save the $

but... i'll be into a co-op in a year (10 Grand), and then the track lock will be going in, and a ton of other stuff, but until then...

$900!! It would be easier to find a whole track lok rear end than doing the swap
