Noise/vibration from steering when turning left

Postby madbilly » Tue 06.06.2017, 16:44

Hi everyone,

My Elan became a one-car orchestra at the weekend! Amongst various sounds that I recognised was a whining/rubbing noise that I could also feel through the steering wheel. It only happened when the car was hot (had been out in the Provencal sun all day) and I was turning left at moderate speeds (>30 mph but below 70mph - too windy round here to go any faster!).

After a read through various forum posts I found the following possible causes:
[*]Front brake hoses, wheel arch liners or something else is rubbing on wheels or tyres when turning (I will check this first!)
[*]Worn wheel bearing (I would assume front because I can feel it through the wheel)
[*]Severely worn brake pads (but I don't hear this noise when braking)
[*]Seized calipers (I also have a chirruping sound when the car is hot which I think is the brakes)
[*]Gearbox oil low
[*]Worn jackshaft bearings

I didn't find anything about steering rack or power steering pump - is that because they can't cause these kinds of noise? What about exhaust vibration, could I feel that through the steering wheel?

Anything else I should look at?

Cheers,
Will :)

Results from the short amount of time I've had to spend on this:
- Nothing obvious has been rubbing on anything, which is good news
- The wheel bearings aren't obviously worn, but I need to turn them with the discs off to be sure
- Brake pads aren't seriously worn, but measuring them won't hurt
- LH caliper is obviously seized on the sliding pins, I'll have to remove it, clean up the pins and holes as a temporary repair; longer term I will fit refurbed calipers (or perhaps something bigger!)
- Gearbox oil not checked
- No obvious play in the jackshaft; I can move it slightly side to side and trying to turn it I can hear a small click but no movement, so I assume that this is okay

Any other ideas much appreciated.
Cheers,
Will

My bet is on the sliding pins.
I would replace them first and see what you end up with 8)

Me too. Get your callipers working properly and the sound will go as if by magic

Incidentally, was your wheel hot after the drive ?

Unfortunately I didn't check, but it does have more brake dust on it than the other side.

I actually already replaced the pins a few years ago, so I obviously didn't do a good job cleaning up the bores.

You could replace them with anodised aluminium ones and make sure that the (new) dust covers are placed perfectly. Use the correct lubricant as well and you're good to go 8)

Anodised aluminium sliding pins? Or calipers bodies?

And what is the correct lubricant?

nono, just the sliding pins :-)
You need tu use HT caliper grease which does not run when hot. :lol:

I used Mintex Ceratec last time I replaced them and I also have some ATE brake repair paste. I'm pretty sure either of those should be up to the job.

I'll have a look for anodized pins now.
