MYSTERY ISSUE. Doing my head in. Please Help!

[Evo]

Evo,

Is the noise getting worse as you drive it or is it staying the same?

If it is getting worse, the more you drive it, the closer you are to solving the problem.

If it is staying the same, and there isn't that much noise, it will probably be Ok to drive around gently till you get it fixed.

It has gotten a bit worse, but I have this fear that if this keeps getting worse, it will affect the next link in the chain, and so on...
It's just worse the more I go over 60kph. Time to get the book out on "How to drive like Grandma".

Not sure if it's good or bad news, but the issue has been somewhat narrowed down.

It's on the driveline behind the clutch.

More to follow hopefully in the next day or 2.

So may very well be something to do with the rear diff then........... i guess fluids had been done fairly recently?

Any chance of recording the sound and putting on y-tube or similar?

Fluids were checked, all nice and free from particles.
Shaft is coming out tomorrow and being checked properly just to be sure.
While shaft is out, going to get rear jacked up and see if there any play on axles, pinion, gearbox output, etc...

I would say very good chance, but I'm not sure how to do that sort of thing...

Cheers,

Any news on the rig Evo?

Well lucky enough, a very good mate (that I worked with many moons ago) who has been away for a LONG time is back home in Perth now, about 15 mins drive from me. That's who said to bring it round for a look.

He drove, straight away after hearing it, eliminated diff, bearings and clutch.
Took a long time to remove the tailshaft (extremely tight, even rattle gun couldn't budge them) but he somehow managed.
Both uni joints are completely shagged.

BUT

He is going to replace them, and do the shaft flip to allow more clearance over the crossmember, then test drive it.

If the noise is there, he said it might be because of 1 other thing I didn't notice/realise....

The lower trailing arms are longer than standard, and other than being dirty, my mate said they look new...

Went back over my paperwork from when I went back to the suspension place for panhards and steering damper, and they also have put down longer lower trailing arms to clear long range sub tank drain plug and correct pinion angle....

FARK SAKES!!!

He has measured and compared to another GU, and these are (according to net check) 11mm longer, heavier duty, but also are apparently supposed to help with correcting pinion angle after lift...
All a bit confusing.....

Should know more tomorrow as he could only get 1 uni joint today, so I left the Troll with him until tomorrow arvo...

Should know more then...

Suspense is killing me!

Cheers

Looking promising mate

Maaate I hope you and your mate are on to it

How much lift does it have? To need longer lower arms? Lower arms are on outside of the frame and would clear tank. You usually only need to replace the upper arm on the tank side with a bent one on a tall lift.
Good to see you found a problem though
