Steering clunk when manoeuvring

[Magicman]

Any one had it? Not the Akerman effect from the tyres, this is an audible clunk slow maneuvering with full or near full lock on. You feel it through the wheel as well.

That is the Ackerman effect isn’t it.
Tyres skipping feels like the suspension is clunking.

No it's definitely not I can feel that as well, this is more a definite one off clunk than the akerman juddering

One of my cars had a clunk, its steering rack was out of alignment. They replaced parts of the rack

Could be a swaybar endlink too. There could be something that's not torqued down correctly.

Bring it to the dealer if you're able to replicate it for them.

I recall one of the euro guys on the forum had a clunk, it turned out to be an under body tray that was flexing, needed additional fasteners IIRC

Thanks

Mine does not like absolute full lock - clunk then but absolutely fine if you just stop a tiny fraction short of full lock.

Sounds similar

Sounds similar

It felt more uncomfortable than in any other car when I did it so never done it again

 

[Wonza]

Same. Clunk only on full lock.

 

[Kimmax]

Can confirm clunk on full lock. Regardless which direction. Easing into the "end" doesn't produce a clunk

 

[JWJ9000]

Same here

 

[Magicman]

I'm assured by both my dealer and lotus themselves that this is normal 😳🤷🏻

Full lock when reversing in my 2004 996 C4S gives an unpleasant dragging, scrubbing feeling - down to combination of steering geometry and camber when on full lock. I've also had a clunk on full lock on other cars and it's never worried me, don't think it is anything to be concerned about - will let you know how it is in my Emira next week.

The scrubbing sensation is the Ackerman effect due to geometry, the clunk is something different

Thank you, great fact - every day is a schoolday! It was an old Celica I had that had a clonk at the end of the steering travel. Unlike many many things in life or a bad round of golf, despite the clonking the wheels never came off...
