Hi all
I'm still getting that occasional burning smell a bit like burning rubber. I can also hear a whining sound (from the front of the car?) that follows the speed/pitch of the revs.

I was thinking it could be one of the belts. I have recently replaced the cam and balancer belts along with the tensioner bearings and idler pulley but I haven't had the aux belt or pulleys/tensioner done yet.

A couple of garages have looked but have found nothing wrong. Does the aux belt sound likely or could it be something else, perhaps gearbox, diff or transfer box? I can't see how those could account for the smell though. I also get an occasional rattley sound from the front nearside and a little bit of noise from the offside as well.

Help....

As you say it smell like rubber are there any marks on your tyres.. ?
Nothing to indicate scrubbing. Sometimes I smell it when driving from cold and pulling away slowly in a straight line, without going over bumps or turning the wheel. Because of this I doubt it could be tyre related. Thanks though:smthumbup

I forgot to say, I found the problem, or rather Mike Ritchie did. It was the aux belt tensioner bearing. I replaced it and I've had no more problems

This is a picture of a tensioner

...although it's from a Pajero

The aux belt is the other large belt other than the cambelt, I think it runs the A/C etc. The tensioner keeps it tight and has a bearing in it. My mechanic took the tensioner off the car, removed the bearing and took it a bearing manufacturer down the road and got a new one. It cost me about £5 for the bearing and £20 to fit it.

That's the aux belt tensioner for a 4, though the bearing method is a lot cheaper if you (or your mech) has the time and the tools.

lol, I was agreeing and saying that the link also suggests that the seized tensioner could cause whining and a smell where the belt would rub :smthumbup

No probs, lol, the bearing idea is pretty good.

We had a bearing go on our rolling road in work the other day. The mfr wanted £400 for the bearing and case, we went to our local bearing place and they wanted £19 for the same bearing. One big set of hydraulic pullers later and it was fixed.
