Got my aluminum driveshaft installed. Bought it from Jeff at Jaws Gear...I must say the quality is top notch. Very nice welds, ultra heavy duty U-joints, perfect fitment, weights about 12 lbs...plus it was about $50 cheaper than the competition. Take a look at the pics.
Here was my problem...I knew I had a center bearing going out and the U-joints were worn on the stock driveshaft. When the tranny shifted, there was a "clunk" from both U-joints and at certain speeds, I got a rattling sound from under the console. I replaced my differential with a completely re-built 3.90 ratio with new TRD LSD carrier....everything was replaced except the input/output shafts and ring gear. Within the 1st day, the center bearing noise got worse...there was also a buzzing sound at about 80 mph at a mid throttle setting. The U-jount "clunk" got louder and the shift was kinda jerky.
Considering how much $$$ I just sunk in this differential, I was pissed. I couldn't figure out why changing differentials would cause all these problems. So I decided to go ahead and change out the driveshaft to eliminate that as a problem. I measured the distance from the tip of the tranny output spline (45") to the yoke on the differential per Jeff's instructions and ordered the aluminum single piece shaft from Jaws....got here in a little over a week.
I just took her out for a run...no "clunk", no rattle, normal engine vibration, firm, but smooth shifts. Frigging amazing...I can hardly believe the old driveshaft caused all that crap! Overall a big thumbs up on this driveshaft :thumbup:
On to the install...
