Hiya boys!

 

Bugeye RS 5 speed, 1" lift.

 

Broke at the end of a 14 hour drive. Car gets driven HARD.

 

Started popping, clunking, binding when we came off the highway.

 

Replaced suspect front CV.

Replaced suspect propshaft (it was toast!)

Most suspension components replaced in the last year

Idles fine, coasts with no bind

All gears engage

Rear diff spins free

Clutch has ~ 40k

 

I've had it to the mechanic for a second opinion, they pointed out the bad propshaft UJ.

 

Binds tight enough to stop the car at low speed. Binding much worse when turning.

 

I'm thinking further inspection of engine and tranny mounts? Or front, center diff?

 

FYI this is well beyond typical clapped-out Subie noises.

Will it do it in the air? If you can get it up on stands or a lift, try putting it in gear and cranking the steering to both locks, see if you see anything. That's where I would start.

See anything as in the engine shifting in the bay?

what was wrong with the prop shaft?

 

Torque bind - the VLSD in the trans failed?

is it 'kinda better' when stone cold - then gets bad after 5-10 minutes?

 

if so, points to center diff failure from what I've read.

Stuck spider in the front diff could do that. I've seen seized spiders in older trucks run like a posi from being stuck. Never heard of a Subaru doing it but never know. You say its run hard

Foward U-Joint was totally shot

No, hot or cold doesn't matter.

Auto trans will shear the drum off inside the trans if driven with too much binding. Does anyone know the equivalent failure of an MT stressed internally with torque bind?

 

Torque bind seems the obvious starting point - maybe it's been happening awhile or was happening under the aggressive driving described which precipitated or accelerated the U joint failure and busted some stuff in the trans as well.

 

Never seen a ujoint mess up the trans wxcept shearing off and flailing around and crack the extension housing.

I saw this, dunno about compatibility; http://www.subaruoutback.org/forums/65-parts-accessories-performance/421050-center-differential.html#post4817538
