Been there, done that!

 

Well mine finally drives smooth all the way up to 75+mph and it tracks straight.

I was stoked as soon as I got it out of the alignment shop and they adjusted the toe just a hair. It is so nice to not be fighting the steering wheel as I am cruising down the highway.

Here is a list of everything I have replaced on the truck.
Radius arm bushings
passenger side balljoints
bearings
rotors
tires and balancing

I really think that if I end up buying another one of these trucks that I am just going to overhaul the entire front suspension instead of messing around with things. Its not all that expensive and after having done the work before none of it is all that difficult.

Rotors will be next on my list to replace/turn even though they only have 16k miles on them and I don't drive the truck like my Mustang. lol They are pulsing pretty bad when coming to a stop and I believe they are the culprit to some howling noise I have in the front.

 

How many miles are on your Ex? I think what did the most good on my truck was 1. Putting anti-freeze in tires to aid balancing. 2. Getting rocks out of the spring mounts. 3. Making sure the wheel bearings are tight.
Actually, it could have been any of a number or combination of things!

 

I've got 178k on her now.

Did the anti-freeze really make that big of a difference? I've been taking the truck to Sams Club to have the tires balanced for free whenever I start to feel it.

The wheel bearings is a huge thing. The inner and outer bearings on these trucks are very close together which causes them to wear out prematurely. I've found that running them a little tighter is better than looser. I did bearings and rotors when I got the truck last May with 161k on it and then had to replace the bearings again at 174k due to them getting ATF in them from not draining the auto hubs well enough when I tried to rebuild them. I ended up just swapping out to manuals.

 

Wow, this is a long on-going thread. Here is an update to my shimmy.
I just had the truck in for an alignment, inspection and have them look at the front end for anything loose. They said everything looked tight and not worn out (radius bushings, rod ends etc). But they said the front brakes and rotors needed replaced. While I would normally do that myself, its the dead of winter and who knows when I would get around to it.
Now the truck rides the smoothest it has ever ridden! I think that when they tightened the bearings up after replacing the rotors, and /or the new rotors themselves, whatever, really helped. Oh, and I just got new Michelin tires a few thousand miles ago. I have almost no shimmy at all now. I hope it lasts!

 

Cool, glad you got it taken care of. Thanks for letting us know what the fix was.
