05 f-150 problem

[JA_Texas_Pride]

Ok well I'm having a problem with my 05 F-150 for some resson every time I stop and take off it makes a thump sound in the rear but after I takes off It shifts nice and smooth only when I stop and take off again its getting annoying thanks

Could be the U-joints. Get under there and try to move your driveshaft around.

I know for my F-250 its cause by lack of grease for the slip-yoke. Here is a thread on it :
Clunk when taking off from a stop. ??? - Ford Truck Enthusiasts Forums

But like I said, I have an F-250, so not sure if its the same for the F150. Join that forum and post in the 05 F150 sections and you'll get your answer. Very good people over there FULL of awesome info.

Goodluck

Our work 04 does it. Idont get paid to maintain it so I havent checked into it, but its probably the ujoint or dshaft needs grease.

My 05 SuperCrew 150 was doing someting similar to what your describing. Turns out there is a service bulletin about this problem. It has to do with the computer controlling the transmission shift points. Shouldn't matter if the vehicle is out of warranty or not. Have a dealer run the VIN for this. Also if you have the 5.4L there is one for it running too lean and pinging. Ask me how I know...

Pretty easy to pull the drive shaft and lube the slip yoke splines, some even have a grease fitting.

Not sure if the F150/250 runs a 2 piece drive shaft, but if it does, you may have a bad/worn carrier bearing. When you put a lot of torque on the shaft(like you do when you take off) it may be "bottoming out" inside the carrier bearing housing. If the truck has a long wheel base, it will beat up a carrier bearing after a while. As far as the yoke goes,you can tell they are worn when installing new u joints. Most shafts have both a front and a rear one or several that are all serviceable. Good luck with it, Texmex.

My company runs all Fords and we have had this problem on almost all of the from 05-07 yr models. It' always either the U-joint or the yoke.

When did you last change the differential fluid?

How many miles are on the vehicle?

Rear end "thumps" often turn out to be diffy problems.

Be well

There's a TSB for this problem. It's TSB 04-26-6. Get some PTFE lubricant (Ford makes some specific), remove the driveshaft and lube the slip yoke with the stuff. Should fix the problem.

Got a V8? Changed the spark plugs in it yet? Don't try to do it yourself, and make sure whoever you take it to knows exactly what they're doing. No matter what, you won't have the truck for at least a day for this job...

If you've replaced the u-joints then grease the yoke & you should be fine.

My F-150 did that.. the dang leaf springs got loose ..and were missing some noise reducers between the leafs..

I'm curious, why couldn't he change the plugs himself?

to properly check the U joints you have to raise the rear end so the tires are off the ground

You can set the parking brake and put transmission in neutral also.
