u-joints need replaced from time to time especially on lifted or wheeled trucks. For those of us that have a 2 piece rear driveline we have 4 u joints in all. has anyone had the need to replace the 2 middle joints. I seem to have to replace my rear ujoint (one by third member) about every 18 months but seem to never touch the two in the middle u-joints by the carrier bearing. Just wondering if anyone has ever needed to replace those two.

 

No I never have had to do them either. I have had to do the hanger bearing though, big money. I am rebuilding another truck and plan on making it a single shaft.

 

If you're having to replace your rear joint that often, something is wrong. I have 218,000 miles on mine & have NEVER had to replace a u-joint. Do you grease them when you change the oil?

 

i replaced both front and rear u-joint in 2004 and did the rear joint about 18 months ago i would guess. Even with a 4 inch lift and wheelin it quit a bit with 33s wouldnt render a u-joint replacement every 18 months to much?

 

a locker will eat the ujoint up quick thats probbly why you need them so often

 

aaaaha that mite explain it Toy-Skitzo. I replaced stock rear end after it chipped pinion teeth. And had a "tru-trac" installed (which acts as a locker on flat/even ground although it dosent grab at all during daily driving.

 

Those are the double cardan joints and they share the bend, so dont get near the wear. Very back is usually the one to fail, if any do fail.

 

Adjust you pinion angle to point at the center joints, and use a nice syn grease after every time you wheel.. I have never had a toyota u-joint go bad, even wheeling and lots of driving, 35's, 33's,... etc.. .and the TT is a LSD so it wont affect your u-joints. Just good grease.
