Shocks & tyres

Post by Andrew n Mary » Thu Sep 04, 2008 3:48 pm

Anyone know much about dodgy shocks and how they effect tyre wear?

In May last year I had an accident and a number of components were replaced under insurance on the front drivers side of the car: a new shock; steering rack and a bits of suspension. The near side was not effected

when on a flat road there is a slight pitter patter from the front and I have found a year later, that the driver’s side front wheel has developed flat spots all the way around, like a 50p. I took it to a tyre shop and they said this was due to the shock being worn out, but said it would be the driver’s side shock that caused it. The driver’s side shock is new and was replaced, it’s the near side that’s old and possibly warn out

My question is…I would normally replace both front shocks at the same time, but the drivers; side is new. Is an old warn out shock on the nearside likely to effect the drivers side tyre?

If it isn’t, then I feel it might be a red herring, there may me something wrong with the repair or wheel alignment etc rather than a shock. I hadn’t considered the disparity in the shocks up until now anyway, so will do something with them, but am concerned that may be another inherent problem.
Any ideas?

Shocks should be replaced in pairs but I can't see why the N/S one should damage the O/S tyre. Some people have had these symptoms with the 195/70 tyres - it went away when they fitted 215s all round.

Hi Anrew and Mary,sorry to hear about your problem.Your O/S shock is about 15 months old and could be faulty.The originals generaly last longer than replacements.
How many miles since you had the bump?.
Did the body shop Jig or Drop test the vehicle?.

Totally agree when changing dampers they should b done in pairs, even now I would buy a brand new front pair and start again...
