Bumpsteer with lift

Hey everyone
I have a 14 dcsb tacoma v6 4x4, i installed the following
Bilstein 5100s front set at 2.5 inch lift
bilstein 5100 shocks in rear with 1 inch lift block
285/70/17 goodyear wrangler duractrac tires

My question is now my tie rods have a steep angle and i get a lot of bump steer.
Is there any bump steer kits that will help limit this or is there a better way to set up my truck to eliminate bump steer and make drive better.
I dont off road the truck is just for looks as my daily driver.
Thanks Adam

 

Did you have the front end aligned after the lift? Sounds like a caster issue you're describing.

 

Yes the truck was aligned and all in spec, only happens with driving over bumps the steering wheel will jerk one way or the other. If no bumps then drives fine

 

It could partially be the tires. Mine tend to want to follow imperfections in the road. Do you have the caster numbers from your alignment sheet? It's possible that if they just got the caster within spec, you may feel some of the differences in the road. Caster is what makes the vehicle track straight when going down the road. The closer it is to being out of spec, the more it will travel around the road.

It wouldn't surprise me at 2.5" that you would be feeling that. When I was at 2.5" it was too far out of spec to get the correct alignment without installing adjustable ucas.

 

^Bumpsteer is not correctable with caster. It's a different issue.

Reducing bumpsteer would require reducing the rack length or moving the rack down. No kits I know of are available for the Tacoma. Clearances are also pretty tight: the tie rod can contact the sway bar if you attempt to move it higher.

The 6" drop-bracket lift systems are perhaps less susceptible because they have replacement spindles with shifted tie rod attachment points.

 

I blame the sway bar...

 

The sway bar actually helps with reducing bumpsteer. Bumpsteer is at its worst when the two wheels are fully flexed in opposite directions.

 

Thanks for input guys would having an alignment and adding caster help reduce the bump steer or would stiffer sway bar end links help
