Hello All-
I know that this has been discussed many times. No real answer in any of the 15+ threads on the subject. Hopefully this thread will lead to find the reason that this is happening...
The clunking started shortly after the install of my Billstein 5100's with stock springs on the third height perch(2.75"). I have checked the usual suspects such as the sway bars and end links to ensure thy are torqued down properly. I even greased the rubber bushing that holds the sway bar to the frame. I still have the clunking sound. I had a mechanic look at it and could not identify the source of the noise.
I can replicate the noise very easily by taking load off the front suspension and rapidly loading it back up. From a dead stop, I rapidly accelerate to 13-15 mph loading the rear suspension and letting the front end come up, once the front end is peaking before it has a chance to naturally level out, I press the brake pedal at 50-60% creating a nose dive. I will get a clunk clicking sound as soon as the weight shifts to the front and the truck is diving- then as soon as I release the brake pedal from the nose dive and the weight comes back off the front suspension I will get a second clunk and click.
I started thinking about the design of the 5100 shock with the adjustable spring perch and wonder if this could be the reason that many of us have experienced the noisy 5100's. I am wondering if the softer stock springs are loading and rebounding and moving the perch off of the adjustable snap ring for a split second. When this happens the perch is creating the noise as it slams back in place.
Please chime in with your experience on this particular setup and if you have been able to resolve it, how you did it.
Thanks!
