 Post subject: Why is my mini tilting?!

I pulled the mini down to the workspace today and egads it tilts!
There is a significant lean to the passenger side, with a noticeably smaller gap between wheel and wheel arch on that side.

At the same time I noticed a knocking from the front passenger side wheel
The photos attached are of that wheel.

There was a broken cable tie (?!) there and it just doesn’t quite look right to me.

Is a person much wiser than me able to determine if there’s anything to be concerned about on those photos? Do they offer a hint as to why the car is leaning?

It seems to be tilting both front and back wheels on the passenger side. I’m baffled. I don’t mind the tilt as long as it’s not a sign my wheel is going to fly off.

Thanks for any thoughts.

That is pretty vital running gear in that area, you'd be wise to strip it all down regardless if there's a probem or not and check it all over and renew anything in need. Eg new wheel bearings and brake hoses and check over the brakes. It all looks quite old.

Yep. I'm guessing the nylon(?) ball joint cup has worn thru. And dirt has probably entered the CV where the boot has slipped off.
Time for a full rebuild methinks.

I would be checking the knuckle joint area. Most likely area to be.
Looks like a long time since any servicing has been done though :shock:

Thanks guys loads of food for thought. Handy pics above too as I’m a complete novice.
Yes it was stored in a barn for 10 years or so, and the dust is impressive.


If the back is tilting too does it have the same bits that’d be causing the issue?

Yes. The strut rod has a similar ball on the end & plastic cup in the suspension arm.
The never get lubricated when in service, so have a pretty miserable existence.

If your car had hydrolastic suspension then the most common reason for tilting to one side is loss of hydro pressure/ fluid leak.

That was my first thought but when I looked underneath I saw shock absorbers - I assume it’s one or the other so the hydro has been replaced?

It looks low enough to be riding on the bumpstops at the front. From the factory the top arms were near horizontal, and yours are quite angled.

If it's dry suspension the cones are probably squashed flat. Being an 850 it would have been dry from the factory

Are you saying you are not sure if it's a hydro sprung car or not? That's an important part of the fault diagnosis. Are there two hoses looping up and then down on either side of the firewall in the engine bay?

Assuming he only has one car I’d say it’s dry

Yes that’s the car. Dry it is then, guess it must be a combination of a few things.
Work to be done! I have a Haynes manual so hopefully I can teach myself a thing or two and solve this one

Here is a comparison of yours and mine (once I replaced the cones). Yours looks to be resting the top arm on the bumpstop where mine has about 2cm of clearance. My driveshaft is more or less horizontal too

Mine was previously that low before I changed the cones and installed some hi-los (which mean you can adjust the ride height). There are some photos of before and after here if you're interested.
