I have been running a 4 inch lift with 35s for 10,000+ miles and have had no problems. Is it likely that I will ever need to replace them?

 

depends on your off road usage.

 

Mudding like once a month

 

I tore my front drive shaft boot yesterday.. I have a 2.5 TF Lift.. 32's

do a search and you will find the front design is poor and a lot of guys replace it.

I'm going to be replacing mine.

 

I have a 4'' lift also with 35's, 14,000 miles, still no problems with the stock units ! Just waiting for them to die, but it's been like 4 years now....

 

I run 35 and a 4 in lift and replaced my rear drive shaft at around 18000. It was covered under my warranty luckily. I will be replacing it soon with a Tom Woods and putting on adjustable upper arms on the back.

 

I also have a 4" lift with 35s. I don't get offroad much and both of my driveshafts have been slinging grease for over a year know. I getting ready to install 2 coast driveshafts and a full set of Teraflex adjustable control arms.

 

Will the teraflex u bolt conversion help fix this problem for the rear on a 2 door

 

Man if you haven't had a problem for 10,000 miles maybe you won't (lol). I had a torn driveshaft boot within a month of installing my 2.5 in lift and also knocked the seal on my tranny pan. With my upgraded 4 inch lift, it's now slinging grease from where the front ds connects with the transfer case. Do you have a manual or auto? That makes a difference.

 

I have an auto and I can here it squeaking but I don't really flex my suspension I just go mudding. How do I know if it's going bad so it doesn't break while off roadin
