June 15, 2006If I'm not mistaken I believe the fabtech lift you have is a combination of a spindle lift and differential drop brackets, which is why your cv angles are as high as much as they are. You could turn the torsion bars back down a little which would help, but thats about it.

June 15, 2006Big Dawg, sounds like your lift has a 4" diff drop and a 6" knuckle drop (one reason why I dislike knuckle kits...I perfer full drops on IFS rigs). Therefore, you had a 2" difference even before you cranked your t-bars another inch. 3" of difference is bad joo joo!
June 15, 2006i talked to the guy and he said that it was a full 6in lift not one that turns up the t-bars to get the full 6in
the ride is awsome in the truck it is really smooth it is the smoothest lifted truck i have ever ridden in
but the cv angles are the only bad thing
June 15, 2006Awsome tutorial. I wish I would have had it about a 3 months ago when i was repalcing my seals. its at stock height so i figure it was just time for them to be replaced 158000 miles. took me forever just to find the right seals had to get them from the chevy dealership since autozone didnt have them. But all in all it really wasnt that bad heck I did it in my driveway with a haynes manuel. But Ill say that I Love GRITS post is a lot easier to follow. And yes I love G.R.I.T.S. too.
June 15, 2006Big Dawg,
Hate to tell you this, but you were lied to. Whether or not "the guy" that you talked to knew the lift kit was not a full 6" or whether he was clueless is beyond me. However, if this is the same guy that told you " the t-bars have not been cranked " (getting that quote from the thread with your cv angles) then he is an idiot and a liar.
Fact is that this Fabtech kit is a knuckle kit. Have you noticed how far your front wheels stick out compared to other lifted trucks? This is because knuckle kits increase the front tracking- something full drops do not do.
Your CV angles speak for themselves. You WILL NOT have those serious of angles ( and yes they are serious- any time two ribs of the cv boot touch , its bad. Let alone your BJ and TRE are screaming for help) with a full 6" drop kit that has only been cranked an inch or so. That kit is pushing 3" of torsion bar crank and the angles need to be corrected.
Unfortunately, the only solution is to "uncrank" so to speak the torsion bars. This is very easy to do, but you will need to get an alignment afterwards in order to preserve the tread and wear pattern of those BFG muds.
Trust me when I tell you this is a knuckle kit, as I am almost positive that is all Fabtech makes. (1000% positive it is on your truck though).
Jon, I have not forgotten about you - today was busy so I will try to get that part number ASAP.
June 15, 2006GRITS, great info in your posts. I never have the energy to type all that, awesome work!
June 16, 2006Great tutorial.
Although, it needs more pics.
June 16, 2006Great Post
we should archive all these type of tutorials under some kind of repair guides thread so they can be easily found when needed..
June 16, 2006Thats a good idea, who do we need to talk to about getting a tutorial thread started?
June 16, 2006Jon,
There are two seals out for the diff. One for late 1998 and up models that features an additional method to control losing oil, and one for early 1998s with 97 parts. I need to know when your truck was manufactured.
Two part numbers are :
New: 12479012 and the deflector for the New :15588337
June 17, 2006I Love Grits,
My truck was manufactured 02/98. Would that be early or late model year.
