Started getting a small squeak/creak on turning right , usually over 20mph around roundabouts, seems to be coming from the rear drivers side of the car, no knocks or anything like that going over bumps etc just a odd squeak/creak now again when the car is leaning around a corner, presume these are the rear hub bushes that will need swapping out or possibly dried out - would it be worth a dowse in some silicone spray and are they easily accessible without ramps?

Any help be appreciated guys... and can you swap the bushes with no post lift, can you do it under the vehicle with it in extended mode?
