I have just bought a GQ SWB

its got a 70mm lift ,When I took it for a test drive at around 90-100 ks it would come in and it just felt like you were running over ripple strips but not all the time also when you lifted your foot off the gas at times you could feel the vibration
I rembered a posting talking a spacer in or on the gear box[ Somewere]
I was not too worried as everthing felt very solid around the tailshalf
its a Auto and the trans has just had a complete overhaul
I'm just not sure as to were to start
Need help
Graham
