Vibration Resolved and rear end questions
Hey Guys,
71 K10, sm465/np205; was fighting a driveline vibration when coasting at 55+mph. bit the bullet and took the driveshafts to the shop last week. Both were roached, splines on the slip yokes were shot. 2 new driveshafts and the vibration is gone. R and S spring in Bladensburg, MD did the shafts. Very nice work. Of course now I notice a large amount (maybe 10 deg or so) of rotational play in the pinion yoke on the rear end. So I'm thinking the gearset is getting a little worn. What are my options here? What rear is in this truck from the factory? 12 bolt? I don't offroad so I'm really thinking a rebuilt stock rear maybe with some aftermarket axles would be the way to go. Any other options for a relatively easy upgrade where I could keep my 6 lug wheels? Thanks!

Re: Vibration Resolved and rear end questions
Some rotational play is required to maintain proper gear lash at temperature.
Was there any up-down or in-out pinion play? Metal shavings in rear gear oil? |

Re: Vibration Resolved and rear end questions
Do you have a lunchbox locker? They are notorious for driveline slack.
