2001 BH5 Etune - Front diff noise...?

Hi all, first time posting on here - im massively stuck on an issue i’ve had with the legacy for quite a while now

 

basically it sounds like a front wheel bearing knackered - but ive changed both and also both cv axles (driveshafts)

 

not only is there a crazy rumbling noise, something is also causing the car to wander when at expressway speeds (like a steering joint is worn...)

 

HELP!!! Surely there is someone on here that has experienced a similar issue

 

Really appreicate any response or suggestions - thanks!!

I’ve literally changed everything that turns - new discs, tyres, wheel bearings and cv axles

 

I let one place have it for a morning and they thought it was power steering related - that could explain the wandering but certainly not the noise...

could be two unrelated  things.

 

pop it up on stands and idle it in gear - poke around with a mechanics stethoscope (broom handle or similar) to work out where the noise is coming from.  Maybe its gearbox or centre diff bearings.

 

Wandering could be rear-end.  Rear trailing arm front bushes shot, for example.

one other thought about steering which is easy to check - inspect your steering rack bushes.  A few years of oil splatter can make them go to mush and fall apart, then the rack slides about.

 

You'll typically feel this on turn-in, though. Feels like steering slips as it loads up.

So, i've figured out - the rumble noise is coming from the front right tyre/rim (but its a fairly new tyre which is odd)

 

As for the wandering steering - i'm going to swap out the steering rack bushes as they're quite cheap and see if it makes much difference

 

watch this space....

      In lieu of a new Technical board structure being implemented soon, here are the workings for the new FAQ posts to replace all technical stickies, and hopefully most of your searches.
      This is a temporary post because it isn't helping anyone locked away while I'm too busy to finish it.
      Please post additional useful links as a new post for a Mod to add to the list.
      Mods, I've tried to categorise things logically and keep double-ups to a minimum. PM me any questions.
      Cheers,
      kamineko

      I recently imported my dream bh5 in the purple/ blue colour, auto ej206 which I'm fine with, it has 49,000 k"s and upon inspection it has had a centre decat and muffler delete and a back box from zero sports. It's a rev C from 2000 and I'm looking to get a base tune or Remap. I contacted possum bourne here in auckland but they are unable to tune the rev C ecu for some reason? Would anyone be able to point me in a direction of a tuner in auckland? Someone also mentioned on here about project lambda,  I was wondering if anyone has had experience with them and if it's worth it. Thanks guys!
