MOT repair: Nearside Front Drive shaft joint constant velocity boot severely deteriorated

dipsomaniac

My car pasted MOT with a nail in tyre last week.

Not sure if yours is too close to edge of tyre to be fixed.  National tyres will fix for £10 with a voucher off there website but they may insist it needs a new tyre.

Looking at the photo on the previous page I would say that the nail is within the central 75% of the tread, given that it is at the first main tread line, so it is repairable - I would certainly do a home repair using a tar string thingy for a puncture at that location.

Replacing a CV boot in no way justifies the cost of replacing a drive shaft.

You can get split boots which can be put on without the need to remove the drive shaft at all (as per the amazon link previously), but they are not the best and really do not last, so better to get a full boot replacement. Shouldn't cost a huge amount and in a local garage under £150 all in I would have thought. As it is the outer boot it can be done without removing the drive shaft from the gearbox, so hopefully even cheaper.

As for doing a self repair to the tyre, please don't, these kits have been proven time and time again to not be a safe way to repair a tyre. You really don't want to risk a blow out in the future. For the sake of under £25 get it repaired properly.

Evidence please?

My anecdotal evidence is that such a repair lasts the lifetime of the tyre. (40k+ miles in my case).

the screw is in the sipes so not repairable legally

External repairs which the string style is are only recognised as a temporary repair, similar to the cans of goo and is not an approved British Standard BS AU 159 repair. They failed the tests required to pass the standard as they are not safe for long term repairs.

Pretty much all of the kits are even advertised as temporary repairs as they know they do not meet the standards.

Just because you have got away with it does not mean recommending it to someone is the right thing to do, especially when it is safety related.

Thanks for the informed response.

I don't know whether it would (or should) be picked up on an MOT, but that repaired tyre was on the car for 2 MOTs and wasn't picked up at all. (Albeit by then it would probably be undetectable unless you took the tyre off the rim).

When you turn the wheel on full lock does it go click click click.
If not you don’t need a cv joint, just a new boot and grease.
At a local garage I would expect to pay between £50 - £70.
Boot £10 labour £50-£60.

If you could do it yourself get this bit of kit.
Plus get 2 cable ties, strong ones. They hold better than metal clips.

"Nearside Front Drive shaft joint constant velocity boot severely deteriorated"..............boot not CV needed

£80 to get my CV boot replaced. I had my CV joints fail, very noticeable when the steering on full lock and you are going a few mph, horrible knock knock noise. Always worth testing for when buying a second hand car.

Sticky boots = cheap nasty solution.

Replacement one piece boot = proper solution but much higher labour cost.

CV boots were traditionally the MoT tester's friend - easy to knacker with a screwdriver, easy to replace with sticky rubbish, customer goes away happy, garage makes a few quid.
