I have a 700r4 with the stock 2 piece drive shaft shortened and 3.73 ratio diff, and have not issues with drive line vibrations up to 80 mph (have not had it higher than that yet). Bowtie Crazy - Here is a pic of where the carrier bearing would mount in the center of the X of the frame.
Jan 13, 2009 · A vibration froma drive shaft is very rare, unless serious damage was done to the car, example drifted into a gutter or the like. I put the entire left side of my car into a guard rail at 100km/h, walk-away accident, had the car repaired, and I am still driving on the same shafts, no damage to the drive line at all other than suspension.
Jan 20, 2020 · There was even a bulletin to replace a 2 piece steel driveshaft with a one piece aluminum on some trucks. Trucks have been getting longer, and it's cheaper and better fuel economy to have one 6" or even 8" diameter aluminum driveshaft than it is to have a two piece driveshaft, might even need a three piece on some of the newer models.
i was working on my little vibration issue last night with my friend who is a transmission tech at the chevy dealership.....he was telling me i should replace my two piece drive shaft with a one piece aluminum shaft.....cutting out the carrier bracket ect.....he claims the vibrations are caused by the two piece drive shaft and is why theres a carrier bearing.....is there any ill effects of ...
If equipped with 2-piece driveshaft, a driveshaft alignment kit may be required. 3. Although extremely rare, front driveline vibration may occur. 4.
Not sure if there was a 1-piece/2-piece aspect too, but maybe. As far as I understand, if a steel driveshaft and an aluminum driveshaft are the exact same shape, and balanced equally well, then the steel one will vibrate at speed way more, due to its increased moments of inertia. Same thing goes for wheels.
Re: Driveline Vibration « Reply #135 on: October 30, 2016, 09:12:37 AM » I hauled 17 sheets of 3/4" birch plywood to work the other day (not sure of the weight, but about max for a 5/6 drop), and the vibration was occurring at a lower road speed.
Nov 08, 2020 · 1966 Biscayne Has older Cragar 2-piece rims with BFG T/A 245/60r14s in back. Kumho 205/75r14s in front. Tires are at 35 psi. Chevy recommends something in the high 20's. Had vibration at 55 mph that went from nothing, to the-rear-is-gonna-fall-off with a 2 mph bump in speed. Pulled rear...
Causing what is known as a torsional vibration (Torsional vibrations will also be created in a two joint driveline that has unequal angles at each of the "U" joints). Rolling the differential upward will lessen the total operating angle at each end of the driveshaft.
