I have a 2011 F250 with 50,000 km.It starts a violent steering wobble when the front wheels hit a bump.Have to slow down to stop it.I had the steering stabilizer replaced under warranty at 40,000.I.m going to try an aftermarket stabilizer.Any suggestions on what is the best brand?

If you have a violent wobble you've got something more than a stabilizer issue.

Are the wheels, tires, and suspension stock?

KLP

Tires are 305-65R18;wier than stock;about the same diameter.Everything else is stock.Eveything is tight;no loose tie rod ends or suspension parts.

Were the 305-65R18 tires always on ? or has the problem started after fitting them ?

As RS said, check the tires, especially for unusual wear and especially if they were just installed, then perhaps to the alignment shop to double check the alignment and suspension for wear. A wobble that starts when you hit a bump usually indicates wear, but your truck is low mileage and the suspension should not be worn.

Catskinners right on too, something is wrong (duh!), and steering stabilizers might just mask the problem until it gets worse. Best to identify and fix the problem then add a new stabilizer to prevent premature wear.

You didn't mention if your truck is 4WD, but I run dual Rancho steering stabilizers on an '04 4WD Excursion, mainly because it sees a lot of off-road in Baja. I am happy with the Ranchos, but I have never tried others, so I cannot compare.

Hey Cat, I didn't mean it to come out that way. Sorry. I can't remember how many times I've looked at something wrong and didn't see it!

CatSkinner

I didn't take any offense, I realized afterwards that I stated the obvious with no advice what so ever.
