[Slow5.0]

Well today finaly i broke in new TKO500 and new clutch with 500 miles,so i decide to take it little bit over 60mph
And at 87mph whoe car start shaking , i tryed same thing in 3rd,4th and 5th ,same thing, so its not in rpms, its in MPH
When we installed new 31 spline joke for TKO500 i chacked U-joints ,and they were good and tight

So did anyone have this kinda problem with FRPP Aluminum driveshaft

BTW this driveshaft have less than 5k miles bought it 2 years ago
And i'm 100% sure its driveshaft that make vibrations (had experience before with stock driveshaft )

My FRPP driveshaft was bent after I broke my T5. I replaced it but I still have a vibration at 85mph.

i would talk to the people who make or sell the TKO500, and see what their suggestions would be. You might have to have a driveshaft made and balanced for that TKO500

I have a FRPP driveshaft and I think either that or my trans causes a vibration at the same speed. Just FYI but I have not tracked it down.

When my rear ujoints failed, I dropped the Al drive shaft at it came up bent too - they seem to be kinda fragile.......

Is it worth it balance this FRPP driveshaft or i better get new one (really don't wanna spend $230for new one )

if it's bent, it's pretty much toast.............

I had my alum. driveshaft out of my car a few times, I tried to be fragile with it but a few times it got bumped. It seems the car vibrates a lot more too. I think mine is toast also because i've bad problems with the e-brake cable snapping and theres a big groove in the center of the DS. Looks like enough to set it off balance. Sux! But I was always wondering about balancing with driveshafts. How would someone go about doing that if it were out of balance? I'm probably going to be looking for a new one when the money comes along.

If it's straight, it can be welded and machined and then re-balanced. Drive shaft shops specialize in the balancing.
