Transmission "Thud"

Transmission "Thud"
My 2002 Supercrew has developed a sporadic 'thud' in the transmission. It happens immediately when normally accelerating from a stop. Local Ford dealer says they have not heard of any similiar complaints. I do know of at least one other Supercrew owner that experiences the 'thud' 1 out of 10 starts. Any help would be appreciated. The trans shifts fine otherwise.

Are you sure it's in the trans? My 97 F150 SC auto 4.6L 4x4 had a thud noise from a dead stop at about 100,000 miles. It would come and go. Solution: lubricate splines on driveshaft. That took care of the problem. It's back again, but I know what I have to do.
Also, don't believe the dealer when your rear pinion seal starts to leak and they want $350 to replace it. Take it to your local ring & pinion shop and have them do it for $65.
Good Luck!

My trans. is doing the same on my '01 Supercab. It's about the same frequency as you desribed above but I have notived that is is more prevalent on slight uphills. It seems to be down shifting very hard which sends a "jolt" through the truck. Very annoying.
Also, I have noticed what sounds to me like a "dry bearing squeek" comming from the maunal 4WD shifter, but only at high way speeds. Any experiences with this? I don't think anything is worn since it has 1400 miles on the truck.

I just had the same problem with my 99 4x4 SC. I originally had a worn u-joint. So I replaced it, but didn't lube the splines at the slip yoke before assembling. Well in less than a week I installed a 3in body lift. After installing the body lift, I noticed the 'thud' that you described. Well after countless hours of checking everything involved with the body lift to determine were this 'thud' originated from, I finally released it was the slip yoke at the driveshaft. So I removed the shaft, lubricated with standard greese, reassembled, and no more thud. Easy fix, just wish I would have noticed it before I installed the lift.
