Title: Need advice with bump steering and 4in lift
Post by: tmedic on December 16, 2010, 08:10:58 pm

I have an 87 Custum Deluxe 4wd. It has a 4 in suspension lift. Recently it started having bad bump steering issues. Took it to the shop. Now new tie rods and drag link later it's a little better but not like it used to be. While under the truck I noticed it still had the original pitman arm and steering arm. So my drag link is angled somewhat. My question is which way would be better...    The drop pitman arm, offset steering arm , or the drag link that is offset ?

Also check your stabilizer shock and tire pressures.

Stabilizer shock is new and tire pressure is good.

I figured I would weigh in on this since I have the exact same truck and lift as you....

I have the raised steering arm...  4" lift with 33x12.50 tires and I also purchased the dual Steering Stabilizer setup and I have absolutely no bump steer on road ( i don't go offroad)

it's definately the steering arm giving you an issue  and adding the stabilizers definately help...

I have pictures if you need a look see  just PM me give me your email and I will send some over...

Thanks
Mike
