Steering wheel kicks back when in a tight turn (like a U-turn)

Recommended Posts

I have a 05 987 and I've noticed that when I'm in a tight turn (like when making a U-turn) the steering wheel kicks back and a "klunking" noise can be heard (in unison) coming from the wheel on the inside of the turn. It almost sounds like the wheel is catching on something over and over again. Any ideas? I'm guessing it's a suspension issue, but, I'm not sure.

Thanks in advance,

Jason

My 987 S does the same thing ... I've never been able to get a satisfactory answer ... I have 19" wheels, do you ?

Thanks for the response. I have the Boxster S II 18" rims. I wonder if this is just how it is? Seems odd to me though.

I think it is probably the tire scrubbing because of impossible geometry in tight turns. A limited slip diff (if you have one) will make it worse.

My 2006 does this as well. Always takes me by surprise even though it does it every time I turn the wheel to the max position.

I had my geo done this week and was told by the specialist that its due to the angle of the wheel on the inside and outside of the turn being at different scrub angles. This is a result of the toe setting on the geo and the caster angle. The noise is the inner wheel scrubbing or hopping when on full steering lock , reducing lock should minimise the noise. The 19" wheels or wheels with bigger offsets due to spacers etc will also exhibit more significant scrub as the tyre flexes less on the 19" wheels and the increased track with spacers makes the problem worse. The inner and outer steering ball joints on the steering rack are prone to failure (mine was changed at 40k ) so it may also be worth checking the front wheels for any play if you are getting a knock on lesser steering angles.
