I have a '97 Lariat Flareside.. When i take off from a dead start there is a thump coming from the rear.. i can hear as well as feel it.. anyone have any ideas on what it is ?? i thought there was a recall on the Leaf Springs.. i contacted my local dealer.. gave them the VIN and they said it didnt affect my truck.. so anyone who can shed some light... id appreciate it.. thanks

Wow, this is scary! I too have a 97 F-150 Lariat (fleetside) with the 4.6, automatic, K&N Filter, Flowmaster Dual Exh.,the JVC KD-LX1 "el Kameloen", and that same damn clunk!!! Have you found the solution yet? I have read some of the threads on the Driveshaft slip yoke so i'll look there first. Good luck gettin yours fixed!

I have just noticed a clunk too, but it seems to occur on decel.

Haven't heard of the slip yoke problem, but I have noticed the springs are coming "unwrapped".
My understanding is they put a clip on them to keep them aligned, though I'm not sure. I also noticed the isolator between the leafs had come out.

Cobra-You're in Dallas too? I've been trying to hook up with the Fordified truck club. Check the "Events and Happenings" thread.

Welcome!

I had the same clunk. I had the spring clips put on and that wasn't it so they replaced the slip yoke and that was the problem
