Hi, i have a creaking noise coming from my sway bar after changing the bushes. It seems to be moving side ways slightly as well. I have read on forums that when changing bushes lithium grease has got to be applied as well. The mechanic who changed mine didnt use any grease. Could this be the reason. Wouldnt grease make the bar move more?
Is it normal for the bar to move side to side?
Please advise any help will be appreciated.
Many thanks,
David
