Any Mechanics Out There

[GB72]

Have an interesting problem with my Megane and thought I would see if anyone had any suggestions as to what may be causing it before I go back to the garage. Basically rear passenger wheel bearings failed and were replaced. A month later they failed again so were replaced as the new set were supposed to be faulty. A month later they failed again and I was told that the brake disc was warped and needed the full lot replacing. A month later and the bearings have failed again. The work was all carried out by Renault so not going to some dodgy garage. The car is going back in again so was wondering if anyone had any idea as to what may be causing this.

To add to this, a car crashed into that rear side and the first set failed about a month after the repairs were completed. All the work was carried out and paid for under other person's insurance and have since been re-checked by Directline as I thought that this may be at the root of the problem but they found nothing wrong.

It's a french car... there-in lies the problem!

possibly the geometry of the rear axles are out following the knock.

Are the tyres wearing unevenly at all, can also be an indication. worth checking with the car repair garage if they have guaranteed the geometry is all OK.

Other than that I don't know. Is all the work being undertakend by warrantee or are you shelling out yourself?

John.


p.s. not to rub salt in but it is also a french car, as previously mentioned

Garage checked the geometry I believe when I took it back in after the second set of bearings failed.

Some has been covered under warranty following the initial repayment, some I am paying for.

It only takes a one off error during manufacture to result in repetative probs like this. It could be a problem with the seating location of the bearings, or as has been said, alignment prob. I would take it back to the dealer from where you got it, you have enough evidence, and start the long process of getting the car replaced. Its not fit for purpose in my view.

 

[GB72]

Sadly have had the car for 4 years at least and then bought it second hand and this is the first problem it has had.

I think that JohnHG is spot on.

Did they check the geometry crudely as many do.

I would want it checked on a laser-jig as that is the only way to ensure accuracy.

Cant think of another explaination to be honest.

HNJ, the car was fit for purpose at the time of sale and with a used car it would be a waste of a claim and the legal fee. The problem only started after it was twatted seemingly.

 

[GB72]

Thanks for that, will get on to it again now I have the correct terms etc.

Whats got 4 wheels, was made in France and goes WHOOOOOOOOFFF?







Your Renault Megane (on fire)

Did they check the geometry crudely as many do.

I had a company owned Mondeo which had a botched rear end repair. Suspension mounting bushes or something like that were replaced and the rear end not propely set up correctly. I managed to shred completely a set of rear tyres in around 600 miles. Fleet wouldn't believe it, their preferred back street company made a complete horlicks of it. Ford themselves had a good laugh when I took the car in and I insisted Fleet got it sorted at a main dealer as I was raging at my and my familys saftey being compromised by a botched repair.

Still shudder when I think of what might have happened.

Hiya, not good at all matey... consistently bad wheel bearings are caused by the things below (that I am aware of)

1. Age
2. Axle nut not tight enough
3. Rolling car around without axles in, possibly even setting the wheels on the ground with no axles in
4. I suppose the two wheel bearing dust shields either missing or being damaged allowing dirt in
5. Incorrect offset on wheels

Hope this gives you more to think about!! (especially #3, dodgy garage??)

They're out of line.

 

[viscount17]

you need the fore-aft geometry checked as well as the whole rear axle/suspension.

I suspect that it should be done on a proper body jig - fancy a trip to France

 

[viscount17]

oh, and not to put you off Renault garages or anything but a neighbour had a turbo Renault that just died whenever he tried to tow his caravan (many would say serves him right)

it took 8 sessions at the Renault garage to realise that the turbo hose was on the wrong way round - the flange was resting on a smooth coupling

(to be really smug I spotted this and told him but he insisted that it couldn't possibly be wrong as they had disconnected the hose on every visit!)

I follow, I thought we were talking about new one.
