Balancing a driveshaft?

use two large heater hose clamps


thought more people would respond to this thread.


Does it matter where you put them on the shaft?

Why not put golf balls in the tube?, it works for tires! :D
 
What if I drilled a small hole dropped in some bbs and then pluged the hole?

never saw golf balls listed in a repair manual, so no.


Have the vehicle running, and mark the unbalance part of the driveshaft. then you rotate the heaterhose slowly with the engine off and retest until it starts to be balanced
 
Have the engine running and mark the unbalanced part? What does this mean? If its not spinning this won't help will it. and if it is spinning I don't want to be under there! :confused:

Disconnect the rear driveshaft, and jack up the front end.
 
Whaaa? Are you suggesting he disconnect the DS from the rear axle yoke, jack up the front end, and then run the truck? Sounds like a real good way to smash up the underside of your truck, or smash up yourself if you get close to an unsecured, spinning driveshaft. I'm not sure, but I think the deal with the heater hose clamps is, clamp them on, one at each end of the DS, them go for a ride, if you have driveline vibration, loosen one clamp and rotate it a bit, maybe 1/8 of a turn or so? Go for another ride. Keep this up until vibration is minimized. Then do the same thing with the other clamp at the other end of the DL. Some fine tuning of both clamps may be necessary. Keep in mind, I have never done this, but am merely guessing at the way it would be done with hose clamps.
 
I'd just take it to a shop, it shouldn't be more than 20 bucks. I got mine shortened 3.5" and balanced all for $35 at Indy Rack & Axle in Indianapolis on the corner of 38th and Keystone.
 
i forgot this wasn't a professional website. You need to put your truck on a lift before running your vehicle in drive.
All four wheels off the ground. The driveshaft isn't going to be spinning fast.

And always turn off vehicle when replacing fan belt.
 
thats where I had my rear shaft made, they quoted me $75 to shorten and balance. I already shortened it myself now I just need to have it balanced. I will give them a call, i spent all my coin making it legal again so it may be a while. Thanks everyone!
 
You gotta use a vibration monitor. I did it in class a few years ago, it measures the vibration and you have markings on the driveshaft. You spin up the driveshaft and flash this light on it and it tells you where to add hose clamps. I am sure this thing costs hundreds of dollars, so take it to a pro if you want it done cheap.

Heh, they quoted me $80 over the phone, but when I took it in and had it done they only charged $35. :dunno:
 
No i meant take the whole DS out itself, not just disconnect the end at the rear axle yoke. But ya i guess actually drivin the truck would work better. but ya my mistake.
