It may stop vibes but your pinion angle may not be correct which can stress them. My buddy had a tj drive around without vibes. After about 3 to 4 months it slowly started vibrating. Same thing happened to my Jeep before balancer fell off. I may not be right but i strongly disagree with the t case drop with a 4 inch lift. Besides why lift it 4 inches just to lower your tcase 2 inches?

Hahaha all the more reason not to cut corners, ill look into the math behind it. Hopefully it doesnt cost me a fortune to figure out lol

I think this is the first time I have ever heard about something like this how does the TC drop cause all of this havoc? I know guys running them that have never had a problem

Most likely not. It's a very precise task that requires some special tools. If you don't get it right, you could fry your differentials. Unless you have some experience in this area and have the tools, you are better off having a pro do them. At least if something craps out, you arent the one stuck fixing it.

What sorts of things? The biggest problem with lowering the TC is that it robs your ground clearance...so the majority of the clearance you gain with bigger tires (after a lift) is robbed by a TC drop.

Bottom line if you run bigger tires you will want to regear.

DutchmansLJ Yes they will matter with tires and pinion angle as well
02-13-2013 06:55 PM
freeskier Your axles and gear ratios could care less about your lift height...

They are however going to care what size tires you have.

I was informed briefly by my uncle today, that after so many inches of lift, i will need to adjust my differentials and gear ratios. Can someone with more knowledge go a little more in depth with this idea?
