Clunking in Front end while in 4 wheel Drive

[ben beethe]

When I have my 02 in 4 wheel drive I hear a clunking noise occasionally. When it is in 2 wheel drive there is no clunking noise. Is this a very bad sign?

Mine does it too. I beleive it is normal:unsure:

 

[ben beethe]

I have 139,000 miles on mine and it has never clunked until a month ago.

Check your CV's and u-joints then, with 139,000 they may be shot, but I think it's normal.

Thanks for the replies.

How do I tell if the u-joint or CV's are shot?

 

[Johnny O]

U-joint if the driveshaft wiggles when you try to twist it by hand, for CV's find an empty parking lot, put the windows down, drive in a tight circle with the steering at full lock in both directions and listen for clicking or other unpleasant noises.

on the highway in 2wd get next to a concrete divider on the left side of the road / left lane. lower your driver side window and listen for what sounds like a chain sliding loosly over a pipe or a pulley.



vibration in 4wd, really bad like a moaning, or roaring over 20MPH.



What JohnnyO said about the shaft moving by hand.



Bad u-joint.

My just started doing this this morning. Did you get yours fix? What was the problem? Is it transmission problems? I have an 02 with 61,000



Thanks!
