Diff! Help :)

[rollalicious]

Alrigth so I've had my 4 speed manual ke30 for two weeks now and its wonderful! except cornering! it makes this terrible sqeak/whine at pretty much every speed turning left. Sometimes it doesn't it depends on speed and revs not how hard i'm cornering, but last night after a wee bit of a floggin (I'm on my P's :) ) it did it every corner and straight line.

I had been hoping that it would be a wheel bearing when i bought it but I'm 85% certain its all coming from the diff now, and my mechanic shares this view (bearings were checked-not sure how well), the advice being it will keep on going and just live with it, but every thing else on the car is perfect!

 

First of all does everyone share my belief its the diff

 

My options? -rebuild,replace,upgrade, service?

 

obviously there will be someone knowing all suitable diffs and it written somewhere else multiple times but my trolling hasn't come up.

would be keen on a 5 speed upgrade as well

Sounds odd to me... is there oil in the diff?? I assume your mechanic checked that first..

 

Ok, when you turn a corner, the spider gears rotate, any corner at all. They rotate faster as you turn tighter. So from that point of view they should make the same noise left or right.

 

However, the motor does drive one wheel more than the other, driver's side) so it may be that the spider gears are making a noise on "drive only", when you're turning left, and not on "anti-drive" when you're turning right.

 

I've only run across wear-mark noises from the crown and pinion, and bearing noises. These vary with acceleration or cruise & speed. so they might get noisier as you go faster, or noisy speeding up compared to slowing down... but not turning corners.

 

No chance that the backing plate is scouring the drum under load or some odd thing inside the brakes?

 

I checked up rebuilding a noisy diff but it was going to cost too much, up around a grand as it had to be sent out of town. In the end we kept the quiet auto diff.

 

The 5speed is a vital addition, every 4K should've had one!

yes that was my understanding, and it doesn't necessarily do it when I'm pushing it hard! just as likely to do it parking :/

nothing has been eliminated as of yet except that he checked the wheel bearings and should of done everything else but he wasn't my preferred guy so I will take that with a grain of salt

plenty of people in town but a large expense anyway- Bearings wouldn't do anything as it is

it's a 3k, not sure if i could handle a 4 yet :P

 

cheers, any idea is a good one WELDER :D

for now I'll just keep putting it on the stands and going through the bits when time allows. I found time to install the stereo (AM didn't do it for me)

Diffs are a dime a dozen. Just replace it.

just shove a banana peel in it :rolls:

Yeah I will definitely be looking round for a suitable replacement, my clutch started slipping today :'( so a full driveline would be handy :D

I was just hoping there would be an awesome trick to fixing it.
