Found this Noise from rear. - Diff

[swallow_che]

Hi all

I have a question for Noise From Rear Between 25-40 mi/h

It sounds like propeller spinning sound. the spinning noise goes faster and slower as the speed goes up and down.

can hear the noise especially when the car slows naturally by releasing the acceleration.

it is definitely not the hub bearings as renewed recently.

any clues?

Please help!

I can only guess you've checked for obvious things, like something rubbing the prop/driveshafts, and that you've checked the diff oil level and brake discs for warping.

A failing diff bearing (pinion) in a Manta I used to have used to make a whining noise but that would be through the total speed range.

What about greasing the driveshaft UJs?

check the handbrake pads, as the retaining spring pin comes out and the pad edge rubs against the brake shoe

can happen more when going around corners as the shoes will rock outwards causing the scraping noise

That’s not good news then. The output shaft bearings are usually the first thing to fail and make a noise.
It’s normally described as a whining noise.

You may well be looking at replacing the bearings and seals in on the diff.

Ha.. bad news...
it might be it as 200,000km on mileage
i think mine is LSD 3.58 as 1990 Daimler
Correct?

As it’s hard to get used one here in Korea.
I might need to rebuild.

Found this kit on Ebay.

Will it be all needed to rebuild?

And it’s okay to delay till noise gets real bad?
Because noise isn’t that bad now
Some people wouldn’t notice. Only sensitive person notices..

Ok that kit looks just the ticket, though I haven’t checked part numbers. Timken is a good brand too.
LSD is correct for your car.

I guess you can leave it for a while. Worst case scenario is a bearing breaks up/ seizes. But I have not heard of it happening before. But you never know?

changed the diff oil. but unlucky! noise is still there!

I decided to go to a mechanic to diagnosis..

btw.. Mine is not LSD even though it's 1990 Daimler!!!

I see Power-Lock was exception for Daimler only for Korea!!
It says on Handbook... all of you can check your handbook..
It says that...

Ok interesting.
I know there’s lots of oddities for territory specific spec. But why they would choose to delete the LSD just for Korea? Who knows.

Time to repair my Diff. But, since mine is non-LSD even though it’s a Daimler (only for South Korea.)

I think it’s better to find a refurbed Diff with LSD and exchange it!

But it is hard to find good one with good price and shipping to here will be another challenge…

anyone can source me a good one?
