I've got a harmonic hum at about 75-80 thats been around for a while now, and its gotten worse after this summer. I'm suspecting its my u joints and want to put some high quality Spicer U-joints in. I can get Spicer parts through work and probably with a discount, just need a part number of which u-joints I'm gonna want to replace both my rear ones? I've heard non greasables are stronger??? Should I go with greasable or non greasables? I really oughta do my fronts one of these days too so if anyones got the front axle u-joint part # as well, thatd be great.

 

Spicer P/N 5-160X are greasable. I've not had a problem with the greasable "U" joints as long as you greased them on a regular basis.

Check the carrier bearing and bushing as well.

 

No carrier with my regular cab

 

bump, anyone got the non greasable rear u-joint part #s? Or any # for the the front axle?

 

Looks like the 5-801X is what you want.

Kind of wild, that is the same joint my 2nd gen uses, just replaced mine as well.

 

Excellent.
I need to replace mine as well.
Where do you buy them when you can't order them through your work?

$30 seems pretty cheap.
