While tryin to do some trail blazing i put my jeep in 4low and developed a loud clunking sound when letting off the gas. Any ideas yall? My buddy who pretends to know machinics was saying it was a toasted front U joint. Could he be right this time?

Thanks

 

Jack up the front end and support with stands. Turn the wheels to full lock and rotate the tire looking at the axle shaft u-joint. Chances are the needle bearings have turned to dust. If so, replace & enjoy.

 

I hope that aint the case, thanks though! Going home this weekend so i'll be sure to check on that
