Wheel hub nut torque

[Jackie]

Long shot I know but does anyone know the recommended torque for a Renault Megane 1.9dci Berline Air rear hub nut or a ref to a site with this info..cheers... J

I have a Megane II dci estate which I imagine would be the same, but have never got around to getting the Haynes manual.

You can, however, download full workshop manuals etc from http://www.electronicmanuals.co.uk/renault-megane-inc-scenic-workshop-manual-p-275.html. It costs a tenner but looks well worth it.

Edit - have looked and it only seems to cover models up to 2003 - you don't say how old the car is but if it needs attention to the rear hubs I guess it might be older.

Sorry bought new in July 2001. Thanks for the info .......J

Your local Renault dealer will tell you........[:D]

280nm or 207 lbf ft

But you already know that don't you John R [;-)][;-)]

Some of the workshop manuals seem to be on here:

Downside is that some seem to be in Serbo-Croat, or summat!

Quite amazing what one can find on the Net, these days!

And even better if one happens to be a polyglot!

Mugabe is in Lisbon. Does the tightness of your nuts matter?

Anyone with mechanical sympathy knows instinctively when a nut is tight enough, torque wrenches are for sissies.

Tighten it until it breaks then back it off a 1/4 turn [:D][:D][:D]

Can you give me the Catalan for that please, Ernie. That is what she might have meant.[6]

Our last 2CV had rear brakes shoes with some kind of iron filings in the material which always made a squeeling noise when braking.  When I decided to cure this by changing the shoes, I couldn't get the hub nuts off to get at the drums  - Gawd knows what they had been originally torqued up to.  Even my local Citroen dealer was defeated.....  [:(]

Can't claim to be intimately acquainted with 2CV rear hubs but generally in such situations I find an angle grinder is pretty persuasive [;-)]

Edit:

Defeated by something THIS puny, (11th item in list) surely not [:-))]

Do they do a version in chocolate?

[AnOther]

No but I believe they come in Dolly Mixtures [:D]

Thanks for the info folks. The Renault Forum info given (280nm or 207 lbf ft) was for a some other model and not the Megane though it may be similar I suppose. The bearings appear to be parallel and not taper. I have recently had the bearings replaced as they were very noisy and they are of the sealed type, one at the front of the hub and one at the back with no gap between them. There is a grease cap but no grease in evidence. I suppose not needed if they are sealed types.
The garage tried to rip me off by telling me that the shoes were worn out and would soon need changing which is why I took the hub off to have a look, lots of life left in them. Only 80,000km on the clock.
In the absence of torque information all I can do is tighten up the nut, has a nylon insert, and check for slop with the wheel on whilst making sure there is no noticeable drag.......what do you think?.....John not Jackie and sometimes known as JohnRoss... so there! 

PS The site http://renault.profitux.cz/Technicka_kniha/RN1D2B3A.PDF gives a torque of 175 N/m for a Megane 1.6 Coupé maybe I should go with this?

By your description, the nut is obviously a Nyloc type and thus self-locking.

That said, the correct and recommended proceedure for Nylocs is to fit new each time they are removed: i.e. they are sacrificial.

Since the wheel bearings are not taper, then they are designed to provide self-adjustment of end float and not therefore rely on a specific nut setting to accommodate wear: remembering that most taper bearings use a castellated nut or some form of lock washer with tabs to lock the nut once the correct end float has been achieved.

The secret with all high tensile steel nuts is to bring them up to the point were the threads jam: and not to the point where they start to fail!

Use the Megane 1.6 Coupe setting: and if a new Nyloc hub nut is not available, I would probably order one and pro tem, lock the nut by indenting onto the shaft with a small centre punch.

175Nm is the correct torque for the rear hub nut.
