Live axle wheel alignment on a fury
MK9R - 26/8/09 at 07:58 AM

I had a a bit of a prang last weekend and the rear axle now seem to be pointing to one side very slightly. The Fury had a lower leading link and a upper trailing ling each side and a panard rod. The only link that is adjustable is the panard rod, does this only adjust and control the lateral movements of the axle??

Yes just lateral adjustment on the panhard rod.

If it was straight before the accident, then something is bent, you shouldnt try to adjust it out on the suspension, instead find out whats bent and fix the real problem.

Could you not remake the trailing/leading arms to be rosejointed, that way you could move one side further in/out than the other.

This is obviously assuming that it is still safe to use the existing components!

Yep panard rod adjusts it lateraly, you may find you have just bent the fixing on the rear of the passenger seatwell, it's a stud that the panard rod fixes to, mine came loose the other week @ 110 chasing a motorcycle and needless to say i sh*t myself, i would check the fixing first, then check the arms.

Sounds like it's not the only thing that wants checking Is the axle off to one side or out of line ?

No, you shouldn't rose joint the sylva leading/trailing arm rear suspension (apart from panhard rod). It relies on compliant rubber bushes to work properly, rose joints would cause cracking of the axle or brackets.

Everything looks straight, it may have been like this before the bump, i don't know as i never lined it out before

Hi Austen

First you will need to establish whether it's just the whole axle off centre or whether it's an alignment problem with the arms IE thrust line. Or whether the axle it's self has a bend. You ll need to find out which area the problem lies in to cure the problem and get it setup correctly.

The arms could do with converting to adjustable ones but without rose joints. The axle casing can be realigned if it is bent and even have the toe in and camber set into it but all dependent on it's alignment as it is now.

The jigging of the chassis was not that accurate when built so more than possible for the axle as a whole to be not right before the accident.
