GEN 1 Slapping Sound after replacing shocks

[MFNG]

Hey guys just wanted to see if anyone has encountered this after rebuilding their shocks.

I had the OEM Gen 1 shocks rebuilt by Texas Shock Works. The original shocks I had were low perch and the rebuilds are mid perch - could this be a factor in this “slapping” sound I’m hearing?

The rebuilds ride 1k times smoother, but the originals that were pretty much all blown were silent and didn’t make this springy slappy sound I keep hearing. The springs on the coil overs have roughly 55kon them. I did t replace them with this rebuild - maybe I should have?


I bought the truck used and have never driven a Gen 2 eaither so don’t know what either are like when brand new. Is this normal? Anyone else encounter this?

Who did the install? Sounds like something was left loose. Pull the wheels and start grabbing at stuff, look for anything that is loose. Check all of the fasteners that are removed during a shock R&R.

I did the install.

that thought occurred to me as I am not a pro, but I torqued everything pretty damn good I thought.

The bottom main strut bolt that connects to arm calls for a lot of torque? Don’t know exact ft lbs but it is a lot! Maybe check there first

Read this thread most say to replace bottom bolt instead of reusing

"Slapping Sound" is a new one...
How loud is it, can you isolate front/rear or L/R?
Is it possible you moved the rear E-Brake cable and its slapping against the leaf?
Up front, did everything go together normal, hats are all sitting the way they should?
Is the rubber bump on shock shaft all good?

406 ft lbs or inch pounds?
