When I am taking off from a stop and disengaging my clutch there is sometimes a clunk before it actually goes in gear.....Its like my truck starts moving and then it slips clunks and starts to move again. Is this my U-joint or tranny slipping??????

 

slip yoke probly most ujoints make noises under motion like under power. but i wouldnt doupt your u-joints are dieing being your lift and tire chioce probly a good idea to replace them anyways under maintness

 

so I read up on it and I found that I can temp fix it by greasing it but I want to fix it permenantly...how do I do that???? Any pics of the yoke would help too.......

 

Damn, mine kinda does that too, but only when its cold...makes me wonder

 

It's the ranger driveline clunk. You can lube the joint and that will fix it for a couple of monthes.

 

So, would it be a good idea to replace u joints...I got 55k miles, I'm sure will doesn't have much more

 

Opps...I didn't see Will's post about greaseing it. I suppose you could replace them but the clunk will be back eventually.
