Travb2007 Posted December 19, 2008 Share Posted December 19, 2008 s90.photobucket.com There is the audio clip... it is on a 77 280z with a 5spd with bad countershaft bearings. Have 2 4 spds on the way but wanted to know if this is tranny or wheel bearings. also if it is rear wheel bearings how do you replace those?

Lukaniuk Posted December 19, 2008 Share Posted December 19, 2008 Wheel bearings are pretty easy to rule out. Jack up each corner and see if there is any movement side to side, or top to bottom with a good tug and pull on opposite sides of the wheel.

Travb2007 Posted December 19, 2008 Author Share Posted December 19, 2008 No movement on wheels think this could be the tranny the countershaft bearings are thought to be bad as at idle it makes a wierd sound push clutch in goes away. oh and moves with rpms Quote Link to comment Share on other sites More sharing options...
Lukaniuk Posted December 19, 2008 Share Posted December 19, 2008 Ya it sounds like its the tranny to me. especially if the sound moves with RPM and not speed. I would try swapping one of the two 4 speeds you have coming and see what happens. It really doesn't take too long. I had a 5 speed in my car at one time and 5th gear went. The transmission shop wanted 800 to fix it, so I just put the original 4 speed back in. I like the 4 speed and I still get fairly decent mileage on the highway.
