Default Shaking front end - Excursion

I have had my tires balanced and rotated too many times for the shaking in the front end to be tire related. My EX has around 95k miles and I am wondering if something has worn out in the steering/suspension system? Keep in mind the EX is built on the F250 frame. Any ideas from you Ford boys?

All it takes is a little slop in a tie rod end to create shimmy. Try a touch more toe-in..loads the components. Old solid axle systems had "caster shimmy" if you tipped the kingpins back too far. Shimmy is a harmonic resonance, often with lotsa possible causes. The one main thing to find out..is it "up and down" or "side to side"?

Slop in the sterring wheel, or slop through the steering wheel?

Here's the few EASY things to check.

1) Ball Joints...Hear any "popping" or "grinding" sounds? Jack up the front corner and see if there is play pushing the tire in & out(hands at 10 &2...push hard feel for wobble).

2) No Slop in the front tires as listed in Step 1?...but steering feels really "loose"??? check the Steering Box / Pitman Arm assembly. Again...EASY to do. It's on the driver's side. The pitman arm pushes and pulls the tie rods from the Steering Gearbox. the shaft comong from the Steering box to the Ptman arm has splines. (32 or 34) THEY CAN & DO WEAr out (especially if there is a lift involved) You can grab the Pitman arm and try rotating it like an accecellorator on a motorcyle...If you have ANY play in it...you are going to need a new Steering Box & Pitman arm... (approx $600 if you have your own mech. $800 from Ford).

I would suggest getting it aligned at a shop that has pros doing the job....and lets you ask the guy to check the pitman / tie rods.... and he'll know about Ball Joints...(the Ball Joint if upper or lower will show a little rust if it's not too bad on the on that is bad.) These are all items which a $50 alignment Tech has to put his hands on one way or another.

Let us know what comes of it.

Time for the F/E re-build. Ball Joints, tie rods, etc.
If you go to a dealer, expect a price tag of $1,200,
give or take a few.

Tireless...Is this a Diesel? If so, what year?

Reason? I'll use the 2000-2003 7.3 Powerstrokes as an example...

THAT engine had a lot of weight. In 2000-2001, Ford had just a single gas shock supporting the entire frontend weight of an already heavy front end. Those two years ate frontends for lunch. They did finally start putting a coilspring along side of the gas shock in 2003...but still...eats front ends (but not as bad).

If it is diesel...and you plan on keeping the truck... I highly recommend having a second shock (dual shocks on each side of the frontend) installed. It will help with the sprung & unsprung weight of the frontend...especially when driving and not on a rack.

Let us know

Thanks for all of the advice guys. The Ex is a 2002 V10 model, no lift kits, absolutely stock. I know an alignment shop with a mechanic that owns an Ex......I think I will start there since I long ago quit doing DIY stuff on my cars.

On the other hand I need to think about trading it in for a new Expedition EL model. This is the longest I have owned a truck in 20 years.

Don't listen to Bug. Whatever you don't don't put a "steering stabilizer" on the Excursion. It will make it drive like crap.
"STEERING STABILIZERS" don't do anything to "STABILIZE" the "STEERING" the that truck.

Hey...Tireless...That truck NEEDS a steering stablizer. It should of had one from the factory. (If it is 4x4)...even a two wheel drive on a truck of that size, it could only help. And it's cheap!

I remember your advice re: steering stabilizers. I didn't do it since I have been waffling on owning this current truck much longer. If I go the truck route again I will absolutely follow your sage advice and add that feature.

BTW - around noon today I cruised through Team Ford in Marietta's car lot.......I doubt they have 50% of the inventory they used to carry a few years ago.

Brother, whether you have been exposed to it or not, a large portion of the suburbs of Atlanta were bought with money made in the housing industry. They are sweatin. The things going on now will reshape atlanta's economy and unfortunately, ford and chevy will be reshaped along with it. If I wanted a new ford or chevy, right now would be the time to go get it. They would almost pay you to take it off the lot, but there is a whole lot of difference in the excursion and the expedition, with little change in mileage. I'd put a steering stabilizer on the ol ford and she'll drive like a whole different vehicle. Tight as new. In about another year the new diesels will be out in all the full size ford and chevy SUVs, and a gas burner will lose half it's value overnight. The steering stabilizer will be less than 150 installed by your ford dealer. Pocket change. Do it.

For what it's worth, I had a serious vibe/wobble problem on the front axle of my '03 Ram 2500. Turns out the tire pressure was a tad too low. Aired 'em up and problem solved. Have you checked that?

Seacraft - I work near Marietta.

GW - I have checked the air pressure....good idea anyway.

Bug - after posting the last comment I went back to Team Ford and walked around. Two comments....

1) those fools sure didn't act like they would deal on any truck or Exp....WTF. Loaded Exp EL's running in the mid 40's........the guy said something about a $500 rebate....I literally laughted out load.

2) I took my EX Ultimate Limited to the used car guy at Ford and asked for a ballpark quote........$8500 on a truck I purchased for $40k in 2002. Screw them and their prices. That's it, the truck is going to the shop to be worked on and a stabilizer added. I plan on running this monster right into the ground if it's only worth $8500......driving a brand new truck off the lot would drop it's value by $8500..

EDIT - I checked NADA and they put that year and model at $12 to $15k......autotrader had dozens listed in the high teens to low 20's. Hey Ford - you can KMFA.

CAC..good to hear your Mom & Sis are killin them on their trip. Wheeler. '82

Tireless...For what its worth... I just sold my 2000 F-250 7.3 4x4 Lariat with 125,000 for $19,500. To the first guy that saw it.

I doubt the 7.3 added that much value, although people want that engine.

Yep. Let them keep em. Akins Ford up here in the hills will put you in one right. But, unfortunately, there is no market much for the trade. I'd just keep it and drive it. 5 to 10 grand that you would lose by moving to a new ford would be alot of go juice for the ol Fountain.

Just a thought. I have a POS 2001 Jeep Grand Cherokee that was shaking at 55-45 mph. It got worse as time went on. Ended up being the brakes. Jeep even had a class action lawsuit filed against them for the shaking problem. I ended up fixing the brakes and then was gonna trade it in. was 30K new and they said we'll give ya 4K for it. I said you gotta be sh##ting me! Then like a month later going to church the number 2 piston blew. Decided to buy a new engine instead of depreciating. Was 3500K and was best decision we made.

Long story sorry, but hope you get it fixed.
