Has anyone ever had this problem? I have a s14 and whenever I let off the gas in 3rd or 4th at like 3500-4500 rpm my drive line/rear end vibrates any clue as what could cause this annoying vibration. ---

You Need to include more info… Did you recently swap motors, Auto or 5 speed, any suspension mods? aftermarket wheels/rubber/ have you not got an alignment. ---

is anything loose? is your driveshaft bearing shot? what about wheel bearings? just check all the moving components ---

I had what you are describing, but I knew my carriage bearing and possibly my u-joints were shot. Instead of replacing them, I spent the money on a 1 piece aluminum driveshaft and the problem was instantly gone! I have used both the aluminum and the steel 1 pc driveshafts, and the aluminum is DEFINITELY better in terms of no vibration at speed. > [@240sx\_nismo](#): > > i have a stage 5 4 puck clutch and exedy light weight fly wheel i get the same thing only in 4th gear, getting a one piece allum drive shaft put in, hopefully it will solve my noise, also solid aluminum diff bushings ---

I don’t think bing has driveshafts. I got mine from [z1motorsports.com](http://z1motorsports.com) . Good ppl to deal with. Speedy shipping. ---

Varun can get you one from the driveshaft shop. I have a 1pc aluminum one but I still get vibrations on decel mainly only in 4th. I figured it’s a combination of sporty things, clutch bushing’s multi link all that stuff is not oem ride quality. You’ll learn to like it or just switch to 5th when going down a hill.
