    Another drivetrain vibration issue

    And I was on to something! I got it! For the hell of it, I took off the trans mount and put 2 washers in to lift the trans up about another 1/8". Went out on the freeway up to 100 and didn't feel a thing. Turns out the tailshaft angle was not parallel to the pinion flange. I couldn't get a...

    Another drivetrain vibration issue

    thanks for the help, but no, this has nothing to do with the harmonic balancer. this is speed related, not RPM related.

    Another drivetrain vibration issue

    Also, it looks like I may have a problem laterally too. IIRC, the stock crossmember was a bitch to line up with the TKO. I had to cut the welds and slide it back, make a spacer, etc.

    Another drivetrain vibration issue

    So it looks like the output shaft angle is not quite equal to the pinion flange angle. I have to whether change my UCAs to adjustables and/or change the spacing between the crossmember and the tail shaft on the trans. This combined with the run out can cause a hefty vibration.

    Another drivetrain vibration issue

    hmmm I'm going to call the guy that did the rear end work and see what he says. No noise or whining at all, but interesting what you said about the backlash and gear mesh. I just went under the car and pushed and pulled on the slip yoke trying to get it to move in the tail shaft and it was...

    Another drivetrain vibration issue

    I tried a couple different things and maybe noted something valuable. With the car in gear the driveshaft is tight (rotationally) and only moves a couple of degrees. With the car out of gear and the E-brake up, the driveshaft rotated freely 12.7 degrees (measured with a digital protractor)...

    Another drivetrain vibration issue

    Its really the whole car, but more than anything it just feels like the seat is vibrating my ass. Just re checked the driveshaft run-out in a few different positions. at the front, on the other side (rearward) of the weld, it was 0.018" (.047mm) which I believe is out of spec!

    Another drivetrain vibration issue

    Another guys on here that described the same problem said it was the U-joints. But mine are brand new. Hmmmmm

    Another drivetrain vibration issue

    86 GT with 438rwhp and TKO trans / spec stage 3. 8.8" rear with Trutrac posi, moser 31 axles, FRPP driveshaft, Steeda L/UCAs. Everything is brand new and the car vibrates like hell above 85mph. At 75, its perfectly smooth, and by 85, it feels horrible. It's a bit worse under hard acceleration...

    TKO Driveshaft Yoke Strength and Fitment

    OK Ill check. I already checked with DTS and a few other places. Dynotech is within walking distance from my house. The only good thing about living in Detroit is all these places for parts / services are all within a 1/2 hour from me. Since I have a TKO with a factory length driveshaft and...
