Correcting bump steer

I just purchased a 2012 Tacoma double cab trd sport. It has a 6” bds lift, Fox suspension and 35’s. I notice it has a little bump steer sometimes. Obviously it’s lifted pretty good and most likely doesn’t have the geometry it did form the factory. I’m wondering if anyone has had this issue and what can you do to improve it? It’s not bad by any means and if there’s nothing I can do I’m perfectly ok with that.

 

Yeah bump steer is a bitch to pinpoint. But with the drop bracket lift. It's not going anywhere. As long as its not ridiculous and unsafe just learn to live with it

 

Although there are things you can do to try and reduce it. Check tire pressures, make sure they are correct and match. Check bushings and BJs and see if they are good. Tie rods of course

 

Also some people have had luck when added more weight (steel bumpers and skids for example). Keeps the front end a bit more stable.

 

It’s not bad at all. I’ve had a few lifted jeeps in the past So I’m used to it. Just figured the Tacoma would be a bit more stable. But as I said it’s not bad at all.

 

When do you feel the bump steer? Off road, highway and at what speed?

 

I drove it home last night 1.5 hours from where I bought it. Noticed it only a couple times on potholes and bridge joints on the highway. Doesn’t always do it.

 

Increasing caster helps the truck track straight. Aftermarket upper control arms and a good alignment can correct it.

 

it is because tie rods aren't parallel to the ground

 

I don’t know the alignment specs currently. But it tracks and drives straight down the road. Just sometimes the steering wheel jerks when you hit a bump. I was wondering if aftermarket UCA’s would help at all.

 

A good set of upper control arms correct the geometry a bit when the truck is higher than stock. Too low of caster and you will get bumpsteer.

 

I think Where I’m going to start is getting an alignment check done, see where the numbers are at and determine from there if anything is crazy and needs attention

 

That is a good place to start. Remember, even though they might get your caster "within spec", it might still be low. PersonalIy I think 2 degrees and under is too low. 3 degrees and up would be desirable.

 

I have a 6" DB and 35's with no bump steer, either with my old factory uppers or the JBA's I have now. So, most likely something needs adjusting, or has some wear.
