Cheers, Steve. And thanks, 'halfpenny' - I had wondered if there was maybe some sort of physics-related explanation, as it has turned out to be a not uncommon phenomenon.

These bits and pieces arrived from Graham Walker today. Does anyone know how much they charge for new brake discs, pads and dust cover assembly? I may replace them too.

I took the decision to get more bits replaced while I'm at it. These parts arrived yesterday...

Scroate trying to nick very nicely polished alloys gets my vote back in 1983 I was ferrying some (Boy)Scouts to camp and my nearly new alfasud suddenly went all vague . Stopped, spotted 1 missing wheelbolt with the other 3 hand tight. No work had been done on the car since last main dealer service but I had played squash the evening before and although not alloys the wheels had some very nice Pirelli’s on them. Fortunately the dealer at the time in Hull was still open and had a wheel bolt in stock. If he hadn’t he’d have borrowed 1 from a showroom car

Tom
In profile Scimitar wheel studs are a T shape. They push in through the back of the hub and lock in place via a splined section on the shaft of the stud. In my case, the circular flat of the T profile, which prevents the stud pulling through the front of the hub had broken away from the stud part (in a clean, neat circular break) allowing the stud to pull through the front of the hub/wheel with the wheel nut attached to it.

Yes, 'scimitargtc' - I hate to think it, but you could well be right as to the cause. I had popped into a shop half an hour earlier, but only for 5 minutes, and in a busy retail park. I vaguely overheard a guy say something about the car, but a bright yellow Scimitar attracting comments is hardly unusual! What's done is done, I suppose... :roll:

Jim - I'm with you now. Your original question was about nuts pulling through the hub, which is why I got confused! No, the studs themselves seem to have maintained their T-shape (but two of them are distinctly 'shoogly' after taking the brunt of the forces involved).

I had a loose front wheel on my 1st SE5 many years ago. It had scratty looking Princess Anne alloys with crappy old tyres, a combination that no one would have wanted.

Fortunately I stopped before the wheel came off, but 2 nuts had gone. I used 1 each from the rear wheels, tightened up the front & continued on my way.

These things happen, checking your wheel nuts used to be a normal check, like checking the tyre pressures. It's just not common any more. On competition cars, we're forever checking wheel nut torques.

Good luck with the repairs.

IIRC, the problem of self unscrewing was particularly related to coned nuts, so not much heard of since about 1980. It was a major issue with truck wheels, hence those little yellow pointers.

Well, not much to update yet... I'm still struggling to find anywhere experienced in fibreglass repair to do a temporary fix on the wing.

The car goes into a local garage this Monday to have the replacement hubs, studs, bearings, discs, pads and dirt shields fitted, on both sides. Anyone have any pointers on tricky bits to watch out for? I want to give the mechanic as little opportunity as possible to mess up...

Ask for a mechanic with some grey hairs.

Indeed - sound advice! I sourced a suitable candidate and the work will commence tomorrow.
I'm just relieved I got the car there safely, on the shoogly wheel studs. I don't anticipate any difficulties with the work, but I've warned the mechanic about the fiddly fitting of the felt oil seal on the outer wheel bearing. Just hoping he has the right kind of grease for the various bits and bobs too...

An annoying setback today... It turns out the nearside stub axle on my car is of a different size from the offside. Evidently it's been replaced at some point with an earlier, smaller type. So I need to get the larger stub axle and hub dust cap. Graham Walker is currently out of stock and will not be able to send the right stub axle for another week.

I'm going to take the opportunity to replace the brake pipes while I'm at it. I've had a recommendation for Goodridge flexi brake pipes. Anyone know if they're worth it over the standard stuff?

I always fit Goodridge hoses, although I believe they have plated end fittings unlike the HEL lines that are all stainless?

GW is usually cheapest IME.

Tom,

I have a set, still in the box, that I acquired somehow Part No. SRL0202-3P SE5/6 Swaged. Manufacture date is 06/02/2014.

You are welcome to them if you want them, just PM me your address and I will send them to you.

Sorry to see the damage.

Goodridge hoses have been good for me too. :)

We've a local boatbuilder specialising in GRP and he has offered to do any repairs on my car. Not sure how well the skills transfer from boats to cars but boatbuilders might be worth a shout if you are struggling to find anyone else.

Cheers, Jim.

Thanks for the offer, Will. If they're Goodridge and 'good as new', then yes, that'd be grand!
