That makes perfect sense. Alright then, so is there any links to a DIY or any tips on changing it? Cause I have never done it and when I looked at it, I couldnt figure out how I wouldget it out.

 

this is the front drive shaft, which is the double cardan, but the concept is the same.

here's a good one.

tips - mark every relationship - into trans. front joint, rear joint, rear yoke to diff with paint, so you can put them back together in the same position. less chance to introduce balance/vibration problem.

-buy new u-joints with grease fittings.

-put a big dab of grease into the cap whenever you take it off for install. it will help hold the needle bearings in place. its critical that those needles stay in place. if any fall down into the bottom, the cap will not seat, and you'll have to start over.

i did mine a couple years ago, and my 6 inch vise would not press the joint out. i had to resort to a really really BFH to get it out. putting it back together was the same too-tight fit. so i took the dremel and the sanding disk and took off a couple of thousand'ths from the inside where the cap fits. worked good but if you do this don't get carried away cause you can't put it back on if you take off too much. it must be a press fit.

if you don't have the tools or the patience, another option is to buy the u-joints, remove your drive shaft and take it to a machine shop or driveline shop. they would probably charge about $25-50 to replace both joints.

 

Alright then, thanks
