Bumping Noise In Floorboard ?????? - Diesel Forum

knhooper · 02-20-2006, 09:15 PM

Need some help folks. when going over rough ground or hitting a bump on pavement I'm getting a bump in the floorboard under my feet. I've noticed the "torsion bar", I think which runs from the front axle back to two braces that run up to the floorboard have a rubber grommet where they are bolted together. These rubber grommets on my truck are both worn out. Is this what is causing the bumping and if so how do I replace them??

My early 99 at work has just started doing the same thing lately.
I suspect it is the swaybar end links as the rubber bushings are looking pretty bad. I will be tackling that any day now.

My '01 has been doing this as well. I too suspect the sway bar links, but haven't pulled them off yet.

My 01 is also doing that---now I will check them out.

Also check ball joints. Had thumping in floorboard, passenger side ball joints shot.

well the first time mine did that wonderful noise i replaced the sway bar bushings 10 bucks a piece at the stealership.....that was about 10000 ago...well its doing it again so went back bought more and that didnt fix it??? so im thinking endlink bushings also

I'm in the same situation. I've replaced my end links, sway bar bushings and my ball joints are 18k miles old...and I still have the thump. I'll be pulling the sway bar off and driving it for a day and hopefully that will eliminate all of its related parts.

thats what i was thinking today...im going to do that this weekend and see what happens

Mine has been clunking for a while now (front). The main sway bar mount bushings are worn. I bought new ones this morning at the dealer and total came to $28.
Will replace them when the weather gets warm (June).

Am I supposed to use grease in the new bushings?

installking · 02-21-2006, 11:36 PM

they come greased from ford

Jace · 02-22-2006, 09:46 AM

OK, I'll goop on some grease when I install them. (The rubber bushings came dry in the package)

Same here. Dry in package. What if I do not grease them? Will they just squeak?

Jace · 02-22-2006, 06:29 PM

I'll bet they will squeak and eventually the rubber will dry out and begin to tear, crumble, or "smear" onto the sway bar.

I would bet the noise is coming from the stabilizer bar end links. For my 2002 they cost $100.oo and come as complete units..not just bushings. Make sure you torque them per specs and apply locktite if you want . JOHN

Any idea what the torque values are for the end links and the bushing bracket at the sway bar?
