blueskies Posted May 25, 2007 Report Posted May 25, 2007 I have a driveline vibration that was not cured with new ball and trunion joints, and since there aren't any local shops that can balance a driveline, I bought one of these gizmos. If it works, it was cheaper than the shipping to send my driveline away for balancing. Not to mention the time involved in shipping it out. The balancer consists of a clamp, and a rubber tube that has a bit of mercury inside the tube. The mercury spins out to offset the vibration, and constantly adjusts to the variability of the vibration due to rpm, etc. The balancer rubber tube slips over one end of the driveline, and the clamp protects it and keeps it in place. Seller says only one is necessary per driveline, and that it should be positioned about 6" from one end. I'm going to put it on this weekend, I'll let you know how well it works... Pete Quote
Reg Evans Posted May 25, 2007 Report Posted May 25, 2007 I hope it works Pete! My 59 Wagon has a vibration at about 55 mph and it didn't go away with a new balanced drive shaft. When I got this wagon it had a big dent in the drive shaft so I had a new one made. I hope it's not a bent transmission tail shaft. Quote
Norm's Coupe Posted May 25, 2007 Report Posted May 25, 2007 I hope it works Pete! My 59 Wagon has a vibration at about 55 mph and it didn't go away with a new balanced drive shaft. When I got this wagon it had a big dent in the drive shaft so I had a new one made. I hope it's not a bent transmission tail shaft. There's been much discussion over the years about vibrations in the driveline at roughly 45 to 55 MPH from many people. Then over 55 MPH the vibration would stop. Even though I've read most of those post during that time and also made post concerning the subject. However, all of a sudden after reading this one it hit me. As a kid I can remember my father and grandfather making comments about vibrations while driving 45 to 55 MPH in their old cars that were fairly new then (mostly Mopars). All of a sudden I also remember them having the wheels balanced, alignments etc., but yet they still complained/made comments about it. I also remembered when I first started driving and would have the same problems. So, it was evidently a common problem even back then, that's probably why I forgot about it until now. So, based on this, just maybe we are chasing a ghost and never will solve those problems. It may just be the way those cars were built back then. If so, the only way to solve it is to put all modern running gear into the cars. Just an old fart comment here that finally remembered something. Quote
Young Ed Posted May 25, 2007 Report Posted May 25, 2007 They don't all do it. The 50 51 and 54 of Dads are all smooth as can be. Two have OD and one is a standard 3spd. Granted my truck has totally different ujoints and tranny but its smooth too. My coupe does seem to have a very slight vib I've got a supposedly all rebuilt driveshaft that came in a truck load of parts I bought to try out one of these days. Quote
Normspeed Posted May 25, 2007 Report Posted May 25, 2007 Pete, you'll have plenty of highway miles to fine tune it. My vibration happens at 70 and up, I think it's just the mickey mouse rubber boot I made up for the front u joint. Some day I'm going for the late model style ujoints. Quote
Frank Blackstone Posted May 25, 2007 Report Posted May 25, 2007 I hope it is not one of those fantasy fixes that were sold back in the 70's. It had a weight that mounted on a rail that was in the trunk and shifted side to side. It was supposed to counter the forces (?) that caused you to drift in a turn and keep the vehicle level. Never knew if it worked but it looked impressive. Yes , keep us informed as I have a 85 Firebird that vibrates at 55 mph. Good Luck, Frank Quote
James_Douglas Posted May 25, 2007 Report Posted May 25, 2007 Pete, I am somewhat skeptical. If you ever need to send a shaft out say during the winter let me know. I deal with a 3rd generation Drive shaft shop near where I grew up some 60 miles north of the Golden Gate. I would be glad to take it up there and send it back when done. I always get a great job without any problems. As for those with the ball and trunnion from joints, the Desoto and Chrysler larger cars have an output that fits the 3-speed and the M5/6 that uses a regular joint. My car has that as well as the 2 M5's I have sitting in the corner. Some folks can also have an out of balance Drum. The wheel/tire combo may be fine and the driveshaft may be fine, but a hum may not. If you have an issue, seek out someone that has an on the car balance machine and have them check it. You would be supprised at how much a drum can be off. James Quote
Lou Earle Posted May 25, 2007 Report Posted May 25, 2007 48 Dodge- no vib 48 plym convert no vibraton up to 75 that is as high as I have gone 46 overdrtive coupe - no vib up to 80+ 47 sedan various vibration - it might beht e tire even if balanced might be out of round - they are old biasl A model fprd coupe vibration at 55 31truck- none up to 60 I am also suspecting sometimes to much grease is installed in the universal and that causes soem of it Lou Quote
