U-joints??? On crewcab shortbed trucks

[dmaxvaz]

I hve about 115k on the truck and i have gone through 3 or 4 sets of u-joints on the rear driveshaft. are others having this issue with the u-joints on crewcab sb trucks with the aluminum 1 pc driveshaft? right now, it sounds like a flock of chirping birds, while driving it

Mine is doing the same thing, but I'm only at about 65ooo miles.

they usually lasted about 40k, i guess this time they didnt last that long

I just looked at autozone.com and they have greasable u joints for about $26. While that means they would have to come out and get greased every so often, they might last longer.

no, it means that they have a grease zerk to allow lubing without dissasembly i have quite a bit more power (600-650hp) and people say that the greasable ones arnt as strong as the non greasable type, since the u-joint trunions are hollow to allow grease to travel to the cap's needle bearings

Ah. Makes sense. :banghead: Haha Learning has occurred again.

Perhaps the angle or balance of the drive shaft?

Ever think the driveshaft may be out of balance? You never know....

Ive got 153000 on my truck and it still has the OEM joints.

i will find out on monday, when i take the shaft to weller truck and have them check the balance.

 

[SgtKilroy]

Sounds like a plan. Good luck! I will probably do the same thing soon. Eventually I want to get a better drive shaft though. Not too tough of one though. If anything in the powertrain fails, I'd rather it be the driveshaft than the trans or rear end.

while mine isn't a CCSB, my ECSB has gone through plenty of u-joints and consequently, a couple tailhousings too.

Ever nail down the problem?

why do I do this to myself???? I did a search on u-joint trying to find the brand that wasnt grease-able, the good ones. Then I read a thread like this, and I still have my stock ujoints.... is there a 'nervous' smilie?

Same boat, but with 90k.

Have you been replacing them while using the right tools when doing it? They say that the aluminum shafts get damaged if you don't us a press or u joint replacement tool. I haven't had any problems with mine and I run a lifted, big tire, high hp combination.

I think its seal taking a shit or damaged on install and the grease drying out, all the ones I've torn apart only had one dry damage side out of the 4.
