Steering problems when lifting the gas pedal

I own a Defender 90 1990, and when I lift the gas pedal, let's say to change gears, the vehicle steers right suddenly - and dangerously when on the highway!


Any clues?

tks

Do you have truetrac installed in the front?

That can cause some momentary pull with power changes...

How is your steering dampener doing condition-wise? Do you get a lot of bumpsteer over potholes/railroad tracks?

Are you engine mounts still present and attached properly? Check to make sure the hardware is tightened up snug. Sounds like a loose or broken engine mount.

Steering damper is a red herring ... check the condition of everything else and damper last ... the damper just masks issues.

Thank you all for your answers.

I'll go to my mechanic on Monday and tell him about this discussion.

Scary experience this morning on the highway with my 6 year old!

I had this problem recently. It turned out to be a very loose trailing arm nut. A blown bushing would cause the same symptom.

Yes sounds like rear steer to me. Check the big ball point on the rear as well as the trailing arm bushings all round.

Definitely sounds like a bushing issue and, like Charles said, most likely in the trailing arms.

I have absolutely no idea how engine mounts could affect steering...
