I have a 95 F250 long bed, extended cab. When the truck has a twist to it, it pops real bad and loud. Almost sounds like the rear end is coming through the cab.

The way I can reproduce this is like this:
While slowing to make a right turn, which is on a slight incline, I turn and proceed up that incline with the brake applied it POPS or Clunks real loud. It doesn't matter if the brake is on or not. If I go real slow it will not pop/clunk. But if I'm going about 10 MPH, CLUNK it goes.

Anybody ever have a clunck like this?

Have heard similar complaints caused by loose rivets in the frame. Climb under the truck and give it a going over, including tranny and shock mounts. If you find a loose rivet, cut if off and replace with a bolt. Keep us posted on what you find.

 

There was a concern a few years ago that involved the transmission crossmember. The fix was an insulator strip between the crossmember and the frame and new bolts tightened to spec.

 

I've gone over this truck and connot find any evidence that things are moving. There is no disterbance of the dirt around the rivits and bolts. I'm wondering if I have a read end going out?

 

I went Deer hunting yesterday and the same thing happened to my '90 when I was navigating a deactivated road.
Snap crackle pop.

 

This must be a common problem on 90's model Ford's, my truck is doing the same thing. Would love to know the answer to this one.



Keep on truckin' ...Mike

 

There was a TSB about frame popping published in the early 80s and reprinted EVERY YEAR through 2000. It's a known problem, and the cure is to weld the front crossmember to the frame.

 

There was a TSB issued in the early 80's and they didn't fix the problem until 2001?!! Mind boggling!

 

They didn't EVER fix the problem. The body style (and frame) changed in '97, and they quit publishing the old TSB a few years later.

 

I guess it's time to buy a welder... I needed an excuse to get one. I'll weld every x-member on that thing...

Thanks guys for helping out.

 

actually
if you would have read back about this.

Its something that isn't a problem. Its just rivets poping.
They can be replaced with bolt's and nuts.

Look back in the forums for old posts on this.
nothing bad is going to happen from the popping.
ANd the replaceing of the rivits is not nessary, unless you want to get rid of the popping.

 

I wouldn't attempt to fix by welding. The frame needs some flex, you weld it all your going to get is broken welds and a weakened frame. I would go the nuts and bolts route long before dragging out the welder.

 

yea
dont weld it.

honestly there is like a 20 post thread about this back further.

 

I had the exact same problem on my '88 F350 Dually Crew Cab and the dealer fixed it by putting some kind of strip between the transmission and crossmember. Stopped the popping immediately. The transmission still moves as it should to keep from breaking the case, but you can't hear it anymore because it slides easily and quietly. This was done at about 15,000 miles and 100,000 miles later it's still quiet.

 

I have had a similar clunking noise on both my 95 f150 and my 92 ford explorer what it was in my case was the front radius arm bushing although you have a 3/4 ton so you probably have front leaf springs...... just a thought
