2500HD, rear end bucks like a wild bull in powder sand - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The area I live in you will get stuck quicker when it is dry than when wet. We have what I call "sugar" sand and when my 2500HD looses traction in it I get a serious buck from the rear. Is this normal?

A customer brought his 2500HD in (D-max) but his is 4 wheel drive, his did it until he put it in 4wd then no more bucking.

That sounds typical if I understand correctly.

The factory limited slip is junk and its problems are intensified by sand. Change it out to a more durable unit and if the shocks have more than 50-60,000 miles on them change those out as well.

In sand or "powder"... any rear end will hop under load in a big heavy truck without traction devices.

X2. I've had the same issue in my 81 3/4 ton, my 86 cc dually, and my 01 CC dually. There's just not enough weight in the rear. 1/2 tons will do it but aren't as noticable because the suspension isn't as stiff. Its especially noticable on high torque low rpm engines because the wheels brake loose easier.

As far as "work" trucks go I have always had either Dodge or Ford diesel's. The 1/2 ton Chevy's have never worked like this 2500 does that I have. Tough truck, just stay out of the sand!

A ladder bar would stiffen up the rear end and stop a lot of that I put one on my 02 hd and could tell a big dif
