Right cut a long story short. changed my sub frame bushes few weeks ago then had what I thought was a wheel bearing issue. I then thought it could of been a diff bush problem as had a low humming noise, I changed diff oil and put anti slip in as well. Then went to Blackpool yesterday went ok there. got in car to come back and the car when reversing felt like it had a handbrake on carried on and set off I got a loud humming noise and a clicking from centre of car which increase on speed. I think I have a lot of play in prop, as I never had this prop of the Impreza the one on that felt like it had little play. am I right in thinking that even being different prop it should feel same. I am now thinking of changing prop first then diff and bushes as low on money. any other ideas may help my cause.
