skitish rear end

so my v6 saloon galant has started acting up, when i drive over road markings, cats eyes etc the rear of the car gets all squirrely, i went through some shallow surface water on the road the other day and the whole back end of the car slewed around. I went straight home and jacked up the back of the car expecting to find the anti roll hanging off or similar but everything seemed tight with no play, the only thing i did find was some slight play in one of the rear wheel bearings (i have ordered a replacement) but would that cause these symptoms? Cheers for any ideas.

Do you have a good amount of tread on both rear tyres? Also are they inflated to the correct pressure?

The rear bearing sound like it needs changing but I wouldn't expect it to cause the car to get out of shape in the manner you describe. :happy:

Thanks for the reply tim, the tyres were a little low on pressure, 30 in one and 25 in the other, once i have fitted the new bearing i'll take the car out to see if having the correct pressures has cured it.
