So I had some major bumpsteer on my truck, I have since replaced all tie rods, track bar bushing and ball joint, then i got a wheel alignment. That helped a ton. But i still have a lot of bumpsteer. Il have a lot of play in my steering wheel and know i need a new gear box so I am ordering a redhead, changing out the power steering pump too because i have a leak, an doesnt look to be the hoses, they are cheap, so I figured a new pump wont hurt while I am doing the gearbox. Going to change the high pressure hose too. My question is, do you think a new gear box is going to get rid of my bumpsteer, i still have a lot of bumpsteer after the new parts and alignment. While I am doing the gear box, should I order a new steering dampner? Its an 06, 6.0 f350 with 170000 kms (105000miles). I want this truck to drive new again. I have owned it since 145,000km. Pulling trailers the bumpsteer is crazy. I am putting airbags in the back also, but i get bumpsteer with no trailer. What do you suggest I do to get rid of my bumpsteer. The ball joints looked to be changed out, they are in good shape and have grease nipples on them with no play. Did stock f350 ball joints have greaseable ball joints? Thanks!

 

Are you running stock rims, or rims with a non-stock offset?

 

stock rims, stock tire size, i am all stock except an aftermarket coolant cap lol and flatdeck

 

Good on wheels and tires,

My next question is shocks, are they the originals?

You may be on the right track with the steering box and front stabilizer...

 

yes they look original, i actually have new front shocks in my shopping cart online, i forgot to mention that, ranchho 5000x, i am looking at the rancho steering damper, its half the price of the bilstein, is rancho good, or spend the $120 on bilstien? ranch is 55 and has a rebate on top of that

 

I have my original Ranchos, with 287,000 miles. I'm sure they were worn out a long time ago. Personally, I think they are good shocks, I think the Bilsteins ride a bit better, and Fox 2.0 will change the ride completely.

I am looking at Fox 2.0 for my rig, but I have much heavier wheels and tires (commercial retrofit). I would not spend that kind of money on shocks for an otherwise stock truck.

I would probably go with Bilstein, but consider it a personal preference. If shocks are the cause of your bump steer, then new Ranchos will fix it for your next 100,000 miles. And if the cause is not shocks, you will still notice a better ride with a replacement.

 

 

I hear Rancho rebates take forever. And also hear you have to buy from an authorized seller. But if you file the forms on time, you will eventually get the rebate.

And clarify for my ignorance... I think you have front coils. But if they are front leaf springs, aged (loose, disintegrating) spring bushings can cause bump steer. Really would not expect that at 10 years and 100,000 miles, but it is a possibility.

 

dyno, how do you define bumpsteer???

 

yes i have coils in the front, the truck was probably drove hard, was an ex work truck. I only paid $4500cdn for it though, low mileage, zero rust, 4x4. diesel. egr delete.
on the smooth big bumps that dont hit hard, i get no bumpsteer, its the little hard hitting bumps, even small hard hitting, like coming to an old bridge, even uneven pavement patches.

bumpsteer, - you hit a bump and your truck darts to the left or right, then you have to correct it. You think all people are idiots Scott? Bumpsteer is nothing like death wobble to confuse the two

 

i think i will go with the ranchos, i am not thinking its my shocks, rancho are so affordable and such a pretty shock that i will enjoy the upgrade. I am not going to replace the shocks until after i replace the gear box and the rest. Do it in stages to really see what parts made a big difference, even though it could be a combo of things. Wanting to try to really narrow this down to the main culprits for future lol

thanks for the help, been doing alot of research today on these front ends with bumpsteer, and see how so many things could cause it. When i had my track bar removed i could push my truck side to side with one finger, so any bad part up there could really mess things up.

 

I doubt that Scott thinks you're an idiot. It just helps us to help you when we know EXACTLY what your problem is

 

 

Well, the only dumb question is the unasked question...

I thought the question was fair. Especially considering how some of the questions I've been asked here resulted in a change of understanding. Not all, but some did.

 

i disagree sorry, almost every thread i searched about bumpsteer prior to posting my own thread, was always the one fellow like Scott in there asking if he knows what bumpsteer is and thinking the guy is probably mistaking it for death wobble and every thread poster was annoyed lol. Really the name says it all, bumpsteer, pretty self explanatory what it is. I dont see how going over a bump and the steering shooting off could be mistaken for anything else. Dumb questions, get dumb answers, usually these questions come from people who think they are smarter than everyone else just really a pet peeve of mine i guess. I dont see how bumpsteer could be mistaken for anything else. Anyways my rant and back on topic. Thanks for the replies and help. I am ordering the parts tonight and will update how she feels in about a month. Pretty big problem on these solid axle trucks, miss my f150 on the highway!
