Strange 'juddering' when on full lock

[TVR653X]

When I put the car onto full lock, it kind of judders a bit, as if something's rubbing or catching. I know I should know what this is, as I've heard of it on other cars, but I can't remember the cause and the remedy!

Wheel bearing?

Tyre rubbing on inner wheel arch!

Normal? It certainly felt like this, but is it normal?

[The Stiglet]

Not normal, my suspension was ancient when it did this so I replaced it with Gaz Golds and it's never happened again.

If it is that....

Of course it's not normal. Normally it ddoesn't judder at all.

Could also be a broken spring

or a sticking balljoint

or a lump on the tyre

or a knackered steering rack.

could be any of those.

[The Stiglet]

Power steering failing?

Time for a service? Nothing was mentioned after it was MOT'd, but unfortunately I have no idea how much they check in an MOT? Is steering one of them?

Every one of those things should be an MOT fail or at least an advisory.

I've had that in the past. Check for rubbing on the inner arch. It's possible that the arch is out of adjustment rather than the steering.

My car nearly failed an MOT a couple of years ago because of the tyre just brushing the arch on full lock - fortunately I managed to persuade him to look again 1 minute later, after I'd whipped the arch off and put it in the boot while he was testing something else!

Just checking the date, is it April 1st ????

No offence mate but are you serious, you really have no idea what an MOT involves ?

I agree with the rest, if you don't know what is checked on an MOT and are wondering about a serivce or not, then I suggest you get some professional help (a mechanic I mean)

I know a bit, such as indicators, wipers, washers, but not much else. I'm going to get a mechanic to help me. You guys have to realise not everyone has spent all their lives working on cars.

I would suggest you need to learn fast or it'll be an expensive foray into TVR ownership as you'll soon find out mention the name TVR to your average garage and then watch them smile and increase costs. A good tame mechanic, preferably willing to teach you, is a must. It also means that if you can't do things yourself you can't take advantage of ebay or other cheaper spares sources and will pay full retail for parts such as throttle pots from Ford at over £50 but buy a Rover one that is the same for £10 as an example.

As a starter I would buy the Sierra or Granada V6 Haynes Manual (under £5 on ebay) and learn all about the engine. Buy the Steve Heath Bible (about £30 - a good read to learn about the car but I haven't found much use for it on the mechanics side) and read it thoroughly. If you buy the Sierra Haynes manual then this will also cover brakes and most of the running gear. But importantly it WILL tell you what is needed in the MOT and also how to service the engine (ex fuel filter), change gearbox and rear diff oil etc.

Next I would look at night schools for a car mechanics basics course as just learning to service the vehicle will save you a fortune over time. Crux is this is a relatively simple car and engine to learn on so you could have picked the right vehicle, just need to put the effort in.

Some simple jobs are explained on some of the owners websites at the useful links above so also worth browsing those.

Good luck

My guess would be wheel bearings.

I don't think anyone's having a go about lack of experience on your part mate. It's just S's have a habit of being temperamental and a bit of mechanical knowledge helps.
Saying that, I consider myself quite handy when it comes to cars and even I have issues with diagnosing mine. Luckily we have a large group of people on here, that combined, can solve almost anything.

I don't think it will be wheel bearings - you wouldn't have got through an MOT with that much play.

Its probably nothing major - some variation in ride height & suspension geometry each side (tired suspension), plus if the rack isn't adjusted centrally would probably mean when you're at the extremes of steering travel your wheels aren't parallel - so the two front tyres are effectively trying to go in a slightly different direction and are fighting each other for grip. Going straight on / moderate turns you wouldn't notice.

Anything seriously wrong in terms of safety should have been picked up by the MOT tester - thats his job.

The solution would be a full geometry setup - though if you have old shocks it would be worth having those replaced too if you can stretch to it (and the difference it will make to the way the car drives will be stunning).

Exactly - that was why I suggested something silly like a misaligned wheel arch.

However, it could be any one of a number of things, which the MOT should have picked up, but might not have. A service might pick them up, or it might not. Depends how good the individual is... Until you feel this "juddering" and have a look, all you can do is guess.

[Barkychoc]

Yes but a guess from a nice warm armchair is much nicer than a could draughty garage
