9" code k rear end
Hey everyone just wondering if the factory trac lock diff is any good. I just got a quote for $2000 to have the diff re built new gears,bearings,seals and have a new posi installed, i dont want to be ripped off kinda seems steep. Also iam looking for some new gears 3.73 and i cant find them or dont know where to buy good ones. I know i could re build it myself (bearsings seals) just not sure about the gears and track lock.
Thanks for the help
If it was me, I would not spend that kind of money for a rebuild when you can probably order a complete crate built to your specifications from one of the major manufacturers such as the one in this link.



Do the RIGHT thing.
that is WAY too expensive. the raw materials for a ground up rebuild on a ford 9" with a new traction lock is under 900$ any competent shop should have maybe 6 hours into it at 30$ an hour, which would put you just into the 1000$ range.

please read through my tutorial on the ford 9"



this will give you an idea of what is involved and in part 1 at the bottom I go into costs involved and approximate what a shop might charge.

2000$ is way too much for just a rebuild or rebuild with a traction lock replacement get another quote from a different shop.

for 1000-2000$ you can get a ready to bolt in bran new 3rd member and axle depending on options, for 1000$ you could get a ready to bolt in 3rd member itself, for 3000$ you can get a ready to bolt in ford 9" axle and 3rd member complete with rear disc brake conversion.
I was charged $650 to convert my original (9" 2.75 open) diff to 3.50 traction loc by a local racing shop. I got all new components except for the case.

I got a complete rebuilt third member with 3.89 and trak-loc from BILL THOMAS ENTERPRISES for around $900.00. And I didn't have to provide a core.

My mustang is named Beth.

As in

Beth I hear you calling and I'll fix you right this time.
but both the kids need braces and I just can't spare a dime.
Just a few more paychecks and I'll get right back to you.
Oh Beth what can I do? Beth what can I do?
