The rear left wheel makes a dull thumping noise when driving at approx 20-30mph.

The tyres have been checked and a visual looks ok albeit the inside edge is 1mm lower than the rest of the tread on both rear tyres.

We took it to have the balancing checked today and the tyre fitters refused to work on it and told us to take the car straight to a main dealer as they said the camber was obviously not correct.

My questions are

1, is the camber/toe angles adjustable on the rear?

2, has anyone had anything similar? what did the main dealer say?

The car is an 08 plate octavia ambient estate with about 26k on the clock, completly unmodyfied and spends most of its journeys at motorway speeds. The tyres have never been changed and still running on the dunlops that it came with.

Thanks

sounds like the rear suspension is shot . Just had fronts changed on 06 oct vrs with 28,000 miles . Front nearside shock seal had leaked dropping all of its fluid . Car was knocking and jumping around right hand corners . Quite scary . £250.00 worse off for pair of front shocks and problem fixed .

A quick update.

Skoda UK have been in touch with my parents and told them that its the tyres causing the thumping sound, apparently the rear wheels are set with a little camber and due to the tread pattern this is causing lumps in the tread which in turn causes the thumping sound. They were also told that they recommend all tyres to be swapped front to back as today's tyres last too long and swapping them around will stop the thumping feeling but it isn't done during services unless asked for and a small charge may apply.

When you take it in for its service get them to do a full 4 wheel alignment, there are plenty of thread's on here about it

It has just had its 1st variable service at Martin Beavers (main dealer) who said it needs x2 new rear tyres as they are designed to wear like that to improve stability.

Apparently the rear wheels cannot be adjusted so a 4 wheel alignment. Wouldn't make. Any difference

Its still an idea to get a four wheel alignment done though, as it'll atleast show if the

rear is within spec or not.

Wouldn't go to a Main dealer to get it done mind you, as they'll charge an arm and a leg,

specialist with the equipment and data is the way to go.

Rear suspension is adjustable on Octy II/Golf V/Leon II. Revised camber settings have been released.

Have a look on VRStu's site, and search on here for 'sawtooth'.

The alignment won't fix the sawtoothing- the answer seems to be to buy non-directional tyres and swap them side to side so they rotate the other way. My Leon has sawtoothing on the rear tyres, but the tyres are cheap and nasty directionals. They'll be off soon.
