Just want to know if anyone here has damaged their halfshafts. If you have, describe your setup and what happened....

I have seen the aftermath when the grease gets nasty and turns into a sand like goo that destroys the stuff inside the joints. I have personally seen the insides turned to dust.

So that occurs due to contaminatino of the grease only, correct? It doesn't have anything to do with the amount of power being made or anything else driving related breaking them right?

I did this in my 94 LX with the splitport 3.8L N/A, 4R70W, and FRPP centersection.



I left a stop sign at WOT, the tires spun for a few feet then hooked, and POW! The stock front diff mounts allowed the centersection to twist too much, breaking the halfshaft and rear diff cover in the process.

I haven't had any problems since I installed poly front diff mounts and SC "fat shafts".

Yeah....I really wasn't too bummed about it when I had to call home for the truck and trailer. I was kind of waiting for that puny halfshaft to go, I just didn't expect the diff cover to break. :zdunno:

Just had my Passenger side one rebuilt on the SC. Took it in because the boot was leaking. Turns out the reason was that the carrier housings were bent! CVJ Axle here in Denver replaced both ends with new. I’m guessing the reason they got bent is due to the slop in the stock (deteriorated) rubber front diff mounts. With our TCI Street Terminator equivalent tranny, the hard shifts didn’t help it any. Poly or aluminum is the only way to go.
On a side note; 92bird has been running around with V8 shafts in his SC for the last several years. A ~350hp motor, Early M5R2 five speed, 3.27 gears, and lots of spirited driving, should have taken their toll on the shafts if there as weak as everybody thinks. But they are still tight and perfect and will keep running on them with no worries.
