Hello chaps
I bought myself a wrx sti 08 hatch back the other day and on the mot certificate there is an advisory, it says.
Offside front radius arm rubber bush deteriorated.
Does anyone know what bush this is and what are the symptoms of one that's gone bad?
I haven't had chance to get under car and look yet and was wondering if anyone had had this advisory on a car and could tell me which bush is required.
Thanks.

Usually if you go under the front of the car With the car jacked up and the wheels hanging down you'll see the bush on the front transverse link aka arm rear bush split from the center mounting or perished badly.

Thanks for that. Do you know if it's a difficult job to do? And do powerflex sell these bushes?

I fit quite allot of these, Not difficult. I usually do them with the arm still on the car just unbolt it and swing it down on the ball joint. Run a thin air saw blade down the side of the bush case, Carefull not to damage the arm. Then tap it out with a pin punch and hammer. I then have a bush insert kit which in essence is a long threaded bar with two hollow cups on that the bush sits in and tighten the nuts on the threaded bar it pulls the bush in to the arm.

Powerflex do a bush but its a caster replacement kit for them

Do you know what the symptoms are if these are worn out?

I've never had one to the point to show anything major but...
Tyre wear is increased depending on how far its gone, less positive steering input as the bush flexes.

Hopefully it'll be ok for a week or two until I get it done. One other question. Would you know what's the best engine oil for these cars? Mine has forged internals, it was done by scoobyclinic. Was going to give it a oil change but not sure which grade to use.
