[Healeys] Steering Jiggle on and off throttle

[Richard Collins]

I agree re sounding like torque steer related possibly to engine mounts. Take a look at engine motion while parked and blipping the throttle in neutral to see if the engine twists.

 No one's tackled this yet, so I'll take a stab. This sounds a little bit like 'torque steer' that some FWD cars have (though it's been largely eliminated in newer FWD cars). Healeys, of course, are RWD so it's not that, and I've not experienced nor heard of this problem in a Healey. The front suspension isn't linked to the drive train in any way, so I'd check engine mounts; it's conceivable, but not likely the rocking of the engine could cause it to hit the steering column (the carbs are pretty close to it). If the chassis is somehow tweaked it might cause some tracking issues, though it would likely be under all conditions. Presumably, you've checked to assure the steering box is properly anchored?

That's all I got.

I have an early BJ8 that has been thoroughly gone through.  Pretty much new everything.  Recently I have experienced a jiggle/pull in steering when getting on and off throttle, admittedly with a heavy right foot.   Doesn't necessarily pull to one side or the other, just jiggles a moment.  It's an on/off throttle thing, doesn't do it when braking.

I've checked the rear - everything seems tight, and all bushings have been replaced.  motor mounts are good, transmission tension rod/bushings are good.  little or no play in the front end, all new there too.    Front end alignment appears to be good.  Steering box is properly adjusted and has normal "play" for a cam and peg box as with my TR3's and Morgan + 4's.

  It isn't dangerous, but it doesn't feel right.  That said, for all I know, it's part of the "vintage healey experience".  I have 5 other vintage british sports cars and each has their own issues that are part of their charm.

Would appreciate anybody's experiences thoughts.
