70 duster rear brake drum/vibration question
Just had a new driveshaft built by a reputable drive line shop. Got shaft from shop put in car, vib still there. Brought it back to shop saying I want it rechecked. They balanced again .. I reinstalled vib still there. New spider u joints as well. Was like 2000thousands runout on shaft If I recall that’s pretty reasonable.... old shaft was 2-3/4 I had a 3 inch tube built. Used old slip yoke was in good shape. Had to lengthen shaft as old shaft was too short. When I install driveshaft I slide into trans have about a inch clearance to mount in dif so that’s about right. Do t think shaft is in to far it’s sitting where it should be vs barely hanging on like the old shaft. I’m doubting driveshaft as it’s dialed in and been rechecked a couple times. Although it does to me feel shaft related I just don’t know as it’s all within spec ??? Uhg
