ratcheting while turning

While towing 7K lbs and turning at a normal street corner, I feel a ratcheting shake/vibration coming from the rear. I have a 2000 PSD 4x4 with a posi rearend. I'm on the gas pedal just enough to get going, I don't gun it. Is this just the clutch plates in the rearend due to the small turning radius?

Are you using any type of antisway control, or equalizer setup? Does it only do it with the trailer hooked up? What type of trailer and/or load is it?

I am actually thinking that it is the trailer tranferring the noise up through the hitch, you would be able to feel it in the floor sometimes. If it is a leaf sprung trailer and you are making a fairly tight turn it could be the springs and pivots snapping and causing the problem.

It sounds like you need a little friction modifier in the LS rear end. Just get a tube of it and add 2 oz at a time until the vibration is gone.

It's a 25ft toyhauler, I use load equilizer bars and a friction antisway bar. I don't think I hear/feel it when coasting around a turn. I'll pay more attention next time. And I don't notice it when there's no trailer hooked up.

Also look at your shackles and pivots on the trailer, they could be worn causing the noise.

It could also be the tires on the trailer skiding and hopping a bit it a tight turn that is giving you that sensation.

I also had that problem. I changed the diff fluid to the proper Limited Slip type, and problem gone.
