156 loose rear anti roll bar - serious risk?

Noticed a noise from the OSR on the way home last night, getting more noticeable on the way to work today, so stopped off at Alan Gibson Alfa on the A30.

They found that the rear anti roll bar was not attached properly, and they replaced one of the bolts.

All ok now, but bearing in mind the insurance repairers replaced the rear subframe in May, it looks like they didn't torque something correctly, which has now worked loose???

I'm going to go in there tomorrow and have a friendly conversation about it, but in real terms, how serious/dangerous was this problem?

Also, whilst I appreciate things work loose over time, if everything was done up to the correct torque, I would not expect things to have worked loose so soon

PS - asked Alan Gibson for a quote for a 24k service - about 320 - thats about the same as Perrys of Portsmouth wanted for a 12k service. Not convinced they aren't as bad as each other??

Re: 156 loose rear anti roll bar - serious risk?

I would have thought it's a serious issue. It if falls off what would happen or does it just diffuse roll? As an aside, I need to get mine replaced at some point, but wondered what would happen if I replaced it with a stronger anti-roll bar - would there be less "roll" or are they all the same?

Re: 156 loose rear anti roll bar - serious risk?

They do wear, they have bushes to cut done on noise but rather than use a durable rubber Alfa seem to have chosen cheese as the material, I replace 3 ARBs on my GTA.

It won't be dangerous the ARB helps to keep the car flatter by transfering spring laoding from one side to the other, if detached it just won't be doing its job so well and the handling won't be the same.

mojo_jojo, stronger ARB will give you less roll, though there can be side affects, on a 156 it may help to keep things tight as these cars aren't the stiffest but there is a balance, front to stiff comapred to rear = understeer, rear to stiff compared to front = oversteer, cases where you might find an improvement though is where less roll leads to the geometry not going out so much and the car could handle better, you'd need to try it and see, for the two Alfas I have had I reckon a stiffer rear bar is essential, the Alfa is too soft and setup for safe understeer IMO.

Crazed Re: 156 loose rear anti roll bar - serious risk?

Mojo_jojo I was thinking of fitting eibach anti roll bars to my sportswagon, one alfa garage told me that I can't as my car has self leveling suspension and in any case thought they would be a waste of time unless I was doing track days, the other told me they get very good results fitting them and there was no problem me fitting them to my car. Both are meant to be Alfa specialists?????
Any one out there fitted them with what results? Any one fitted them to the self leveling unit.

ee61re I would have thought the chance of bolts etc. falling off, perhaps at speed, so close to rear tyres was an issue. Did your insurers use an Alfa garage?

Re: 156 loose rear anti roll bar - serious risk?

It wasn't an alfa garage, no, it was the insurers local approved place, but their work is guaranteed for 3 years, doesn't affect the alfa warranty, etc etc.

I've sent them an email just now, about that, and that I've noticed some imperfections on the paint finish around the boot, so hopefully I will get a response pretty quick, and get the paint sorted.

No harm done, but I would hate to think its a regular occurence, and someone else might not get a rattle checked out so quickly, and find themselves in a hedge or something!
