Thanks for posting the pictures Dom, that really helps and shows the problem.

That is a problem. Shame you can't make the National :(

It's got to be the cylinders or subframe. Something has got to be out of line somewhere. Hard to see what though...

I still reckon your best bet is to get yours up against another Activa and do some comparisons.

It's odd. Never seem anything like that before...

So it is on the 3rd and 4th of July? As this thread suggests it's on the 17th?

:?

If it is any time after the 5th July I'll be able to make it.

Here's something for you though. I've noticed just now, and once or twice before, but not really thought about it until now, that when I park up in the drive, the nearside rear lifts up. I'm assuming its to do with my 3 point turn in the drive so that when I brake going backwards, the trailing arm design suspension lifts the rear end upwards. The height appears to sit correctly after this has happened, and then it drops back down again, however I'm unsure as to whether it drops back after being driven, or just being parked up. If I remember tomorrow morning I'll check to see if the nearside is still up where it should be or whether it's sunk back down.

Does this suggest knackered bearings in the nearside trailing arm pivot?

Thanks.

The National is on the 17th and 18th July at Gaydon in Warwickshire Dom.

What you describe is pretty normal behavior during three-point-turns although this in normal circumstances causes a lean rather than the levelling out you have there.

I don't reckon it'll be rear arm bearings as they'd have to be very knackered to cause a big height difference and by then, you'd know from other symptoms like creaks and jerky rising and most notably, excessive negative camber on the wheels.

Do you have any odd noises going over bumps?

I may well be up for that then Jim.

I forgot to check my nearside rear wheel this morning. But it appeared to be at the correct height when I got to work, but it was only a quick glance as I didn't have time to have a proper look. It could be due to there being a hill with traffic lights on not long before I get to work which could make the trailing arm lift the rear end. It would be interesting if it decided it was going to ride normally - especially seeing as I've not done anything with it.

What I was describing wasn't caused by the steering in the 3 point turn by the way Jim. I was more thinking that it was the braking in reverse that caused it, as my drive is sloped so you end up rolling backwards at quite a rate, then brake to a stop, which causes the rear end to lift up slightly. It then seems to be able to keep it there. It's certainly very odd.

And noises from the car.. Well there is a deep thuddy type noise from the rear end, moreso when the nearside goes over pot holes and deep grids in the road and so on. I've always thought my rear beam mounts/rubbers needed replacing because of the noises at the back, however could it be a mixture of the mounts and the saggy rear corner?

:?

Thanks. Dom.
