[Supras] Help! New vibration MKIII Supra Turbo

[Bill Wright]

For what it's worth, we have new Goodyear Eagles, balanced by an honest-to-God Goodyear dealership, and they are great.

No vibration in  our Supra (yet!) but I've seen this type of vibration in my Ranger truck and in jack shafts (same as a drive shaft) on some of the boats we sell. This is apparently a very difficult thing to rectify, in my experience. It took my Ranger 3 tries, the third of which was at an entirely different driveshaft and axle shop, before it was cured. In the case of our Volvo-powered boats with drive line vibration, we have had to replace them with entirely new parts, before the vibration improved. So, there is a thought....new or good used replacement. Or, try an entirely different shop. It really seems to make a difference, although I don't fully understand why.

Good luck!
