Hi, I have a '67 Skylark. Previous owner swapped in a 200-4R. I have a driveline vibration at 60mph, I have read a few threads here and will be investigating my pinion angles. However, more immediately, I believe my tailshaft bushing may have too much play. With the slip yoke installed in the transmission, I have measured 0.020" of play at the yoke. No fluid leaking from the seal. Before I get too much further, I would like to ensure this is not normal. Can anyone confirm, should there be any play at the slip yoke when it is installed on the output shaft? Also, where does a fella find a new output shaft bushing and the removal tool for a 200-4R? Thanks for the help!
Responses should be interesting. I can't help you with the play in the slip yoke but I've been chasing the vibration for 11 years in mine. I have the back of the trans and crossmember shimmed up almost to the floor, and with the adjustable upper control arms I have the pinion and the tailshaft in perfect alignment with each other with a 1.8 degree angle on the driveshaft and it's still there, although not as bad as it used to be. Part of my problem is my 4.10 gears, so the driveshaft spins a lot faster than most. And the car is lowered about 1". I can't help but wonder how some of these cars that are really lowered fare in this category. Anyway, the `64-`67 cars have a longer driveshaft, which doesn't help. I've spend over $1,000 on two different drive shafts, one of them is a 3 1/2" 'Nitrous Ready' shaft from Denny's Drivehshafts to the tune of over $600 and that one didn't even help the vibration. Maybe even worse because it's heavier. My next move will be one of these. Expensive? Yes, but I am sooo sick of the vibration that I'm willing to spend the money. http://www.driveshaftshop.com/domes...e-cv-real-cv-in-your-street-rod-or-muscle-car
Get your original drive shaft, have it shortened or lengthened with the correct slip yolk, find a drive-line only specialized shop that does all that and get it balanced. Make sure your rear yolk on the rear end is tight, and the u joynt fits nice n tight. As to your tail housing, it dont have one now that I remember corectly. But first I would pull drive shaft out. and feel the yolk. You can feel if it is worn. I have never seen a bushing on a tail housing cause anything but a leak. The main thing to look at is if it is deep enough into the tail. It should be pretty much all but an inch in. Jack it up with jack-stands on the axle tubes and run it through the gears. You will find the source .
TranStar industries is ware i get anything transmission . Im in CA. It should be contacting the yolk or sock fit. You can pretty much always grab a drive shaft when its in a car and get some slight play. The center support inside the Transmission is real important on the 2004r. About the only thing you can do in the car is upll the valve body and check the bolt in there.
the good news is there is a tool for pulling that bushing. it works super slick and you can leave the trans right in place.
