Why does the floor shake at around 45 mph ?
At about 45 mph the floor starts to shake
near the 4wd shifter if you let off the gas or
go faster it stops? What would cause that
and can I fix it myself? Its a ram 1500 5.9l
Sounds like a bad U-joint or a weight fell off your driveshaft making it out of balance. Search for articles on removing the driveshaft and replacing your U-joint. www.youtube.com is a good place for videos. It involves getting under the truck and doing some wrenching.
Thanks I'll get back to you on how it goes
Could also be a bent front drive shaft if you've been out in the woods or on the rocks.
