aint they like 2800 bucks for a ralliart, or should i just get a quaife, or get the mitsu helical lsd???

 

Could also be tires. Tire vibration will be speed related, driveshaft vibration will be RPM related.

If its just wining and still running why replace it now? Run that ***** till it blows. Personally I'd keep fighting the warrantee issue till I was satisfied.

 

good luck.

 

Well, I guess in theory, springs could cause an issue with the driveshaft.. I know I use to be into Jeeps and all that good stuff and when you lift a truck too much you'll mess with the angle of the driveshaft and yada yada... but I mean, you need some pretty serious lift to do that, so I guess in theory lowering it could have the same effect, but from what I've read the drop on those things is pretty "calm" and it sounds like a bunch of crap.

 

You deffinately DO NOT have a bad tcase. I had a bad tcase in my 04, and its VERY LOUD and very ANNOYING in every gear, even in neutral. It get louder as you go faster, so I can guarantee you have a good transfer case. It may be the driveline, could be tires like some have said. EVOs make alot of road noise...

 

Apples and oranges

Your jeep had solid axles front and rear and therefore a lift or a drop moved the entire axle up or down including the diff, this changed the geometry of the driveshaft.

On a car such as this that has independent suspension front and rear the diff will have never moved with a mild change in ride height, only the wheels moved(and obviously some suspension components) and changed the angle on the CV shafts, but the pinion is in the exact same location it left the factory in so there has been zero change in driveline geometry.

Unless your springs were rubbing on the driveshaft or installed in your t-case there is absolutely no way the springs affected the driveshaft. They "could" affect the CV shafts and in theory affect the Diff or T-case, but thats a real stretch when you are talking about a difference of an inch or so, and you'd know it if that happened as CVs will pop when the angle gets to the extreme to were it isn't running within tolerance. Besides you lowered it and are still within the factory operating limits and still have the factory bump stops I assume.

 

yea i put the bump stops back in when i did thye springs

 

so the whine i have stays the same pitch doesnt get louder in 4th and 5th and it doesnt do it in nuetral , so what else could it be?

 

just an update on things , had all the fluids change with mistsu diaqueen front and rear , and had the tranny fluid changed 2 to chk evrything , there were no chunks or broken parts , wouldnt there be chunks , from the front diff if it was broken?

 

If you touch these cars AT ALL, the dealership reports it to Mitsubishi Headquarters and they promptly grenade your warranty. From that point on, NO dealer can give you warranty service.

That isnt as bad as what Subraru has been doing lately though; when you buy a new STI, they ask if you want to join their "Racing Club". If you sign up, they automatically void your warranty!!!

 

thats insane man
