Help with Boxster suspension query please.

[JJ126]

Hi. This is my first posting. I have a 1998 Boxster 2.5 and I was wondering if someone out there (with a lot more motoring knowledge than me) may be able to help. I've had my Boxster just under 2 years (great car) and I'm slowly working through a small list of mechanical issues that need dealing with. The latest one to come to my attention is that both rear lower suspension arm bushes are splitting. I was going to ask if it is possible just to change the bushes without actually replacing the two suspension arms. If it is possible, anyone know roughly how much it would cost.
Many thanks in anticipation of advice.
Cheers

I think there is a replacement bush available, both in rubber or polybush.
If the balljoint is suspect then exchange wishbones are available from people like Hartech for less than the price an OPC will want.
