four wheel drive?

I was driving my jeep the other day, and i was in four wheel drive. It started making a thumping type sound. I was on paved roads that were dry. It only does it while in four wheel drive. It does not do it in 2 wheel drive. any ideas on what the noise is?

1995 jeep wrangler yj 4 cyl 5 speed.

Welcome, try not using four wheel drive on dry pavement, it will bounce on you....

Nothing to it but to do it.

Four wheel drive is not intended to be used on dry pavement. Switch to 2WD and problem solved.

I don't know where you guys get that you can't use your four-wheel-drive On dry pavement... And telling people to turn the four-wheel-drive on and off as your road conditions change is ludicrous ! There is no way that you can judge the road conditions fast enough to engage and disengage your four-wheel-drive. And if you're at Road speed there's a lot less rolling resistance than when your rock crawling.
What do you think rocks are...essentially natures pavement. You don't go to Moab and not use four-wheel-drive because it's dry rock. I've never gone rock crawling and not used my four-wheel-drive because it's dry rock.
There's thread after thread about how durable the wrangler is... Yet people make it sound as if you drive a couple blocks with your four-wheel-drive on it's going to blow up on you.

Because this is the newbie check-in area, you may not get the answers you are looking for. You have gotten several good answers but you may want to check this forum area to get more info on your particular Wrangler model.

The fact of the matter is that 4WD on pavement is exactly what is causing the problems as described. Rocks are loose, which is good for 4WD.

There's no center differential between the front and rear differentials on a Wrangler like on AWD vehicles. There's just the transfer case which doesn't allow the front and rear differentials to rotate at different rates while traveling at highway speeds and going around corners. This can result in wheel hop while cornering and/or damage to the transfer case because of binding of gears while cornering. Use 4wd on bad roads with confidence and lower your speed.
