lifted X - factory driveshaft U-joint replacement and vibration dampener removal

[malcolmzilla]

Hey Folks,

I have a '92 X with about 74K miles oni it, it still has the stock (no grease nipple) U-joints and transfer case and rear axle mounted dampeners (big heavy rubber mounted things).

Could use some more advice:

1. Although they seem good now, I expect the original u-joints to give it up soon after I have the lift and 33" tires on (based on previous experience lifting j**ps) - what do you guys recommend as replacements? I always like to go with greasable u-joints, but have heard that the grease channels make these weaker than permanently lubed versionjs? Any experice with the Moog / Spicer "heavy duty" models?

2. Can I shuck the vibration dampeners without much adverse effect? (I ask because the bolts are so corroded I may have to cut'em off)

Thanks.
Malcolm

Unless you are putting some serious power to the ground you will never need to worry about breaking a greasable u-joint. The only place that it is necessary to run non greasable u-joints is in the front drive axles. As for the dampeners, if you don't need to remove them, just leave them on. If it is necessary to remove them go ahead, its not going to cause any serious problems. On a lifted X running agressive tires, you'll never know they are missing.

Right on, thanks.

I don't drive that hard. I've been reading those 4x4 magazines too much!
