Hi, i have a 2005 Fx4, with 74,000km and alot of hard miles put on it. I replaced the rear leafs about a weeks ago, my olds ones where sagging. I was wondering how can one tell if the front t bars are sagging/getting worn? How long do they normally last?

 

I am still on my factory t bars at 130K, and Ive been pretty rough on the suspension. It also depends on what rating bar you have.

 

depends on the bar. and if you have them cranked all kinda stuff...

 

My buddies lifted 04 has its tbars already sagging. He cranked them almost an inch and a half. He has around 20k on his truck.
