My buddy has a 2011 250 and is having some weird issues with a clicking noise. It started out when you put the truck in gear (D or R) and touch the gas it would click. Seems to be coming from the middle to rear part of the truck. Now it clicks when he's driving. This all started after he got 35's and a leveling kit. It's taller springs in the front and added a block in the rear. Any suggestions? It has less than 15k on it.

 

Sounds like the U-joints are going out. Lifting the truck puts the U-joints at a greater angle, which shortens their life. The clicking is probably from bad roller bearings in the U-joint caps.

I second that. I think the max angle is 3 degrees.
This is interesting.

From a 2.5" front lift and a 1" rear block? I can't believe that other trucks aren't having this problem? What's the easiest way to check the U Joints?

 

Even though the trucks are high, I believe stock the output shaft of the trany points directly at the pinion of the rear end.

 

Maybe the joint has just setup a ware patern and the change set it over the edge.

 

I have 34k on my truck and I run a leveling kit in the front and 35's. No issues here...

 

Thanks. Another bit of info. He told me he laid under the truck while a friend drove forward and backwards over him (about a foot in each direction). He said if he put his hand on the drive shaft that he could feel it "ping" which was making the clicking noise.....

 

U joints...time for new ones. If it doesn't go away after replacing them, check the drive shaft for being out of balance.

 

I should know this but don't....What's the best way to check the U Joints?

That definitely sounds like U-joints to me. I've had them go out before (not on this truck) and had the exact same symptoms.

Try lubing the driveshaft spline first.

 

I have the Same problem on my truck. I have 43 k on it and it's stock. When I hit the gas everything is fine. When I get off the gas there is a sound of rocks hitting metal under the truck. I asked the dealership and they said its coming from my driveshaft. But they drove an identical truck With the same problem so they told me its normal.... I don't care what they say this shouldn't be happening. Any clues on this?? Should I try replacing my driveshaft u joints???
