Front lower arm rear bush is it knackered?

im assuming this video I took this morning shows a worn bush. Front tyres are wearing on the outside too. Can someone just confirm this isn't normal play?

Both sides similar, all other bushes and joints seem sound.

Those bushes do have quite a lot of movement, I wouldn't say they were knackered until you hear knocking when dabbing the brakes at low speed, or when driving over undulations. That's what flagged up to the MOT person to fail mine last year at any rate. Rolling Eyes

Getting a little clunk almost feel it through steering wheel as I reverse off steep drive onto level at an angle. Could be steering column maybe?

Yes, it could easily be the steering column (lower section usually). Can be like that for a long time before it becomes bad enough to be of concern. Check the steering joints, suspension ball joints, anti roll bar bushes and drop link joints though, just to eliminate those. Thumbs Up

Thanks DN and Eightfoot. Everything else looks tight. Reckon I'll go down the steering column root Union root.
On a side note do these arb bushes look ok?
Is the big gap at back okay.

Thanks for all the feedback - everything but the lower arm rear bushes seems solid. So why are my front tyres wearing on the outside edge? Alignment was done 5k miles back. Looking back through receipts looks like the rm are 60k miles old - that sounds a lot for this car - how long do they last under normal Tarmac conditions?

Was the alignment for just the front - these vehicles require a proper four wheel alignment to run good.

I would check for play horizontally 90 degrees to the chassis as thats where the loading is going to be when the vehicle is moving ie in and out ratehr than up and down.

Mine had a clunk at slow speed and I was convinced it was the front lower arms, new front arbs bushes (which I would have said were okay) cured the knock and I havent heard it since.

Anti roll bar is under maximum torque in this situation, points to arb bushes Thumbs Up
 It can when others can't,
It will when others won't,
It goes where others don't.

Thanks guys here's a pic you of the arb bush. Is that gap at the back an issue?

I would say those arb bushes have had it... Looks a good 1-2 mm gap there.. Which when under pressure makes for a surprising amount of movement.
Cheap and easy to replace and eliminate 👍

I replaced my front rear lower bush with polybush!

Seems to be working a treat. Front bushes were fine.

Lake_district: guessing pushing the polybush in was doable? Any special tools?
Getting the old bast Censored d out must have been more challenging?
