Although the 2CV is [maybe?] somewhat lighter .....which could aid acceleration,up to a certain speed? Although did'nt the Ami [and Dyane] have a higher top gear than the standard 2CV gearbox? T.

 Re: Noises at Speed - follow on from 'Motorway' thread
My Ami has it's original gearbox, and I'm sure the gearing gives it longer legs. I wouldn't mind betting it's more aerodynamic though, but I have little understanding of that kind of thing. (I've recently built two model aircraft, neither of which seem to have any inclination towards actually flying)

 Re: Noises at Speed - follow on from 'Motorway' thread
On the subject of the original question, on an empty stretch of road, try weaving from side to side and see if the noise gets better and worse.
Oddly I had a front wheel bearing go on a non-A-series and it turned out the bearing made more noise without weight on it. ie It made more noise when turning left but it turned out to be the left hand bearing that had gone.

 Re: Noises at Speed - follow on from 'Motorway' thread
Thanks All - I will try out the various ideas....
The car has more to give, no doubt....and i'm not too worried about pushing the engine - it's well oiled and doesn't get too hot....it's more the worry that something is going to fail at speed...or fall off cos of the vibration....it's not that bad, but i am quite a cautious person, so the howling tells me something's wrong, i'm not going to push my luck and take the car even faster - though i suspect the howling may even go away OVER a certain speed....
how long should an experienced A-Series mechanic take to replace a front wheel bearing???

 Re: Noises at Speed - follow on from 'Motorway' thread
Correcting the angle of the dangle for lowering I think. I think the kingpins/steering components are put under strain when lowered without this modification... but the people who actually know will be along shortly! The arm is cut and re-welded at the hub end.*edit* maybe not! Heres a pic from Russ's thread, there are probably more pics on here but this is the first I can find: http://www.international2cvfriends.com/forum/viewtopic.php?f=5&t=1831&start=120 (Scroll down a bit).

Remember the right kilo's min. 35 kg, not possible without the correct tool. Another thing, Ami's are using bigger diameter wheel bearings than 2cv. If you buy and fit reproduction bearings in particular in the rear drums, they have a very bad happy of separating next time the drums are removed (service or repair) SKF won't do this but relativily more expensive. When separating the whole job need doing again, maybe at your cost (man hours) Attachment: P2070052...jpg

Spanners, the law please @Willami the 2cvgb handbook has the invoicing times that Citroen cherged for various common maitanance tasks, front bearings were invoiced at 1.7 hours, nothing listed for rears but replacement and ajustment of the drum was 1 hour Sean
