Can any body tell me if this is normal. I have a 450 Chimaera its lovely. When I accelerate fairly hard it wants to pul to the middle of the road. Its easy to correct but I was wondering if this was normal.

What does the car do while driving normally holding your hands loose on the steering wheel?? Have a look at tyre wear, especially for scuffing of the inner and outer edges of the tyres. This may suggest poor steering geometry. Before spending any money on geometry make sure the suspension bushes are in good order.

Also check tyre pressures and sticky brakes can also cause a problem. It is not normal and should be chceked out as there may be something that is worn and needs replacing.

Thanks for your replys. The car steers straight when driven normaly. Its only done 12k 3 years old. I bought it four weeks ago. I must say the rear tyres seem to be scuffed on the outer edges the front very slightly on both edges I put that down to fast corners and hard acceleration. As I say its only when pushed hard it pulls.

Brakes would be my first guess, then bushes and geometry.

Worst bushes for 'going' are the top front ones which you can see on opening the bonnet.

I had a similar problem when I first bought mine, pulled to the right under accelleration. The dealer had fitted a new steering rack, so I got the tracking checked just in case. I used a computer 4 wheel gizmo place and they found that the tracking was way out and the drive axis of the car was not straight, causing it to pull to one side.

An hour and a bit later and 80 odd quid lighter and its a different car, makes a hell of a difference having all the wheels pointing in roughly the right direction.

Cheers,

Andy

Hey Vince

What happened further on this subject – hope you didn't fly into the kerb and bugger the wheels which is why you're looking for the Griff ones!

Berore having your traking checked have the wishbone bushes replaced. Upper front wishbones are prone to wear.

I was wondering whether you were accelerating too hard out of a roundabout. Because I understand this is what happens when you are showing off infront of other TVR GRIFF or CHIMP owners?

have been having this exact problem with a Griff that I have just bought. It wasn't doing it on test drive, but only since a new (re-conditioned) diff was fitted, as the old one was noisy.
Have taken it back to the dealer + they are confident it is to do with the ltd slip, + are fitting another diff next week which should sort it. will keep you posted

Have had what sounds like exactly the same prob with my Griff. Have just got it back from the garage today, and it is a totally transormed car. It was due to a mis shaped tyre!!, nothing to do with the diff as origionally thought. No idea how that happened between me test driving it, + picking it up after purchase, but another possibility for you.

Hope the dealer wasn't a wrong 'un and swapped a tyre or two after you showed them the wedge and took the plunge?! Just a (horrible) thought.

And front wishbones thmselves seem to be prone to rot -- I just had to have mine replaced when all I went in for was some new bushes...

Manek, could you please give me a ball park figure to replaces wishbones and bushes. This seems to be a job that we can all look forward to at some point.

Sure.

The cost of replacing all eight front poly bushes plus ball joints and wishbones was £421 (incl. VAT) from Peninsula.

A good job was done, the car felt better, and I got a day out in Devon with a courtesy car into the bargain.

Manek,
That's quite a trip for you, any reason why you didn't go to Fernhurst?
