Hey guys,
There's an easy fix to stop the springs from squeaking on the frame stops.
Go to a plumbing supply store(Home Depot has 'em) and get 4 plumbers connectors. I forget what size, but I think it is 3"diameter x3" or 4" long. The connectors are grey plastic, have stainless steel hose clamps on each end, and fit over the frame stops. Tighten 'em down and you fixed for about $20. The set on the '97 lasted the 70+K miles I had it and were still good when I traded it in.
I was told about that "fix" by a Chrysler service rep. after I complained about the squeaking on my '97 3500 at the TDR Nationals in Mesquite, NV and it has worked on my '97 and my '00 trucks.
There's also a letter in a TDR Magazine back in early 1998 about the same "fix".
