Some noise coming out of my rear end

[Stimpy]

Great topic name eh?

Just recently I have noticed that - at low speed - doing a left hand turn and accelerating (even worse up a hill) I get a rhythmic noise (in tune with the roll of the wheel ). It's a difficult noise to describe but it's like the scrape noise if you leave an LP record go to the end of the record and you hear that hissy grind rhythmically.

First instinct - since noise is from rear left - it's maybe the bearings? Or perhaps the diff?

Any ideas forum friends?


Cheers!

Sounds like a worn / dry diff to me.

U/J on the drive shaft away ?

I have the same problem, again from rear nearside wheel area. Mine is intermittent and totally random. It might not do it for weeks and then start halfway through a drive. Doesn't matter if I'm going uphill downhill left or right. Then it will stop after a few minutes as quickly as it started. I am yet to diagnose it and a mate of mine thinks it might be a stone or something in the hub, so when I get a spare half a day I'm going to take the hub off and have a good look. I thought it might be a UJ or bearing problem but surely if it was it would do it all the time?

It would probably be prudent to check the six studs that hold the hub onto the trailing arms as well - you wouldn't want it to come apart as you were driving around a corner!

It might just be the brake shoes touching the drum. If the wheel bearing has some play, it could let the drum to shoes clearance change and create a rubbing noise. Take the drum off to look for witness marks and also check the shoes clearance - and the wheel bearing!

With that idea what I have done is - gently apply the handbrake to 'encourage' the problem but it makes no difference (apart from slowing down!)

Here's where I show my engineeringly infamous ignorance - erm - what's a 'UJ' ?

[Stimpy]

BTW- It being light and now able to - I'm off outside with the jack to do a visual/poke test......

A UJ is a Universal joint. The gadget that allows the drive shafts to turn when they are not axially aligned.

I hope 'Jack' includes 'Axle Stands' especially if you are going underneath!

Check the angle of the rear wheels. Could be the hub working lose . I had this problem on the outside. The hub pulled out so far it pulled the brake cable locking the rear wheel and pulling the studs out. In my opinion this is the most serious fault with the Stag the alloy used in the trailing arm is of such poor quality, especially 40 years on. ps be careful helicoiling the studs as this can augment the problem.

Yep UJ - got that - had to ask my dad!!! Excuse my ignorance.
What can I do about that area? Peel back any rubber gaiters on diff/wheel? Check inside?

I did not use axle stands HOWEVER I just grabbed the tyre/wheel and checked for play which there wasn't. I didn't go under at that point (although I did have a look from the side - not much to see really) - I was in a hurry as I had to pick up my little one from the parents.

Today I've driven miles and miles and it just happens 'now and again'. Had missus in the back of the car (insert your own gag) so extra weight makes no difference - just under 10 stone (140 lbs). Definitely comes from rear left and missus says its like a chafing or rubbing sound (again, like playing off the end of a vinyl record). We reckon it happened 5 times (it's not loud or anything) - in perspective this is in hours of driving - only on corners - only with the foot down - always turning to the left. Most turns that way (or to the right) created no noise at all. So it's rare and not extreme in any way - but bear in mind my proposed route to europe. Of course it might just 'go away'.

There's been some good suggestions here - but now I know what a UJ is what can I do with it, please? :-)

[Stimpy]

ok up on jack - oh and axle stands ;-)

Taken wheel off - all looks ok.

Now I'm going to take the 'drum' off to inspect the brakes - see if its that.

As far as other things everything is parallel - whereby I mean there's nothing unusual about the 'bad' side than on the 'good' side (ie no difference). Ok - take the drum off......

[Stimpy]

Ok had the drum bit off.
Brakes look ok (please excuse my french here but under half an inch I turn to metric 'mm') there's about 3 or 4 mm there.
There is NOTHING visible to seem wrong.

Here's some things I noticed:

There's a lot of play when turning the 'wheel thing' (sorry about ignorance - but I dont know the names).

Then when I reach in there is play between wheel bit and the first rubber 'boot' thing which must be where wheel meets the first part of the drive bit.

I think there was also play further up between first rubber booted bit and heavily rubber covered bit.

Hoping that simply jiggling things around would help end my dilemma.

Nope! Took it out and there it was again - left turn on power and back comes the noise - which now had a slight grind to it.

Here's another clue.

You can cure the issue by taking a sharp turn RIGHT and putting on the power.

Trouble is - that's no good to me - I'd look like the F1 racers as they end their formation lap to get to the start line!
Does that clue ring any bells?

Otherwise - it looks like its over to the professionals/ a professional. Dammit.

I still think it sounds like the diff probably needs some oil in it.

[Stimpy]

Ok - an update.
Today I drove for a few hours and that noise seems to have gone away.

However - the 'take up' clunk seems to be harder ad louder if you know what I mean
Could be that I'm 'paranoid listening' but it sounds quite clunky on the ear take up - specially first and reverse. In fact going from one to another makes me cringe a bit.

How much 'clunk/play' is acceptable?

reminder - this is all at the back of the car.
