Rotational Squeak - sounds like a chairlift

[NearJetties]

I didn’t have luck searching so I’m going to ask. I’ve come across similar issues but none quite like this.

I’ve had rotational ‘squeak’ that I can hear under 30 mph with the windows opened. Unclear if it happens at all speeds but probably does. It does not sound metallic. It almost has a rubbery sound.

If you ski or snowboard it’s the exact sound you hear when your chair goes through a sheave train (the wheels/assembly on the chair lift tower the cable rides in) but is constant.

It’s been happening for a while and has not changed over time. Appeared after wheel bearings were serviced, new drive flanges / c clips and new rotors and pads went on.

I haven’t had a chance to have someone lean their head out but sounds like it’s the passenger side. Nothing obvious rubbing but I should look again.

Not affected by turning, engine speed, or being in neutral. Changes with vehicle speed.

Hallllp, it’s windows down season

Mine was because of the brake dust clip rubbing and causing an oscillating low chirp under 20mph on my 80.

What was it rubbing on?

Front or rear? Asking since the rear of the 80/100 more similar

I’m assuming I’d catch something like this when spinning the wheel while on a jack. Why didn’t I think to do that already face palm

I got a video with audio but it just sounds like a bird chirp.

If not brake related, could be spindle bearing, if you didn't check and grease it together with the wheel bearing (always should). The brass on steel makes a similar sound.

Otherwise, Chairlift is/was a great band, so, lucky for you. (altho I w'dn't call it squeeking)

Not affected by turning,

Could this be rear brake pad wear indicator?

Who did the wheel bearing service?
What other parts used?
How were rotors removed, be detailed?
Was wheel hub surface rotors, butt/mount up to flat and deglazed/de-rusted?
Was wheel hub surface where wheels butt/mount to, flat and deglazed/de-rusted?
Was wheel surface that butts/mount to wheel hub, deglazed/de-rusted?
Where rotor run out?
Any brake pull or pulse?
Can you post a picture of front calipers, showing pads, like this angle:

Was axle needle bearing & brass bushing lubed?
Was each wheel bearing, kept with its race?
Was oil seal, in back of wheel hub, seated flat side out and flush with wheel hub stator ring?
Was wheel hub cavity packed with grease?
What was final breakaway preload?
What was the thickness of snap ring (C-clip) used?
What was wheel hub flange (drive flange) to snap ring gap?

Have you check wheel bearing, for play and is there any?


Sometimes the dust shield on FDS (AKA CV) outer axle seal, is bent and will rub seal in back of knuckle. With pull axle tight with a snap ring to hub flange gap, of less than 0.20mm. Seals rub.
We see back of knuckle, where FDS passes through. Which has and outer metal dust shield, inner rubber seal.

Look close and you'll see the FDS outer axle seal. Outer metal dust shield, inner rubber seal.
