I have an 03 f150 XLT 4x4 and an at wits end here

Everytime I come to a complete stop and gas it my truck clunks an feels like the body shifts backwards

It's hard to explain but it happens without fail Everytime I give it more than a touch of the gas pedal I've replaced my upper ad lower ball joints shocks links and bushings both front hub assemblies and had my truck up in the air about 5 hours on Friday night checking all the linkage everything seems tight and nothing jumps out at me

If anyone has had this problem or any insight to it I would greatly appreciate it

I believe it to be more of an annoyance than anything going to cause excessive wear and tear but I may be wrong just trying to fix my girl right so any help is appreciated

Thanks
Nick

 

I have an 02 and i have a clunck like that also and i believe its the seat bolts in my came loose and it sort if moves a bit still have to check to make sure thts it just and idea to look at.

 

Check your transmission and engine mounts...

 

You may need to lube the slip yoke at the transmission/transfercase! I use teflon grease.

 

Ya I checked all my mounts they seem to be good still so I'll go for some lubage do I have to pull it out again because I did do my rear u joints a few months back but I didn't think I had to lube anything when putting it back not have I ever done that so well see I'll do it at work tonight

Thanks guys any other ideas I'm open to try anything

^This. Get the Motorcraft Teflon lube.

 

So take the driveshaft back out lube it up and put it back?

 

Correct.
