Installed the shocks with king springs all round exactly 2 years ago and they just havent lasted/performed as i thought they would. They've done about 40,000km i think with about 25% of this offroad.
i recently installed a spare wheel carrier which added a bit of extra weight on the back and ever since they have sagged alot- more than they should in my opinion or even with out the spare wheel carrier they would scrub the tyres with a full car load over bumps. i thought about getting 2WD shocks in the back but as a mate tried with the gabriels the spring base welds broke and left him dragging his ass home from a camping trip. see pic

Just yesterday i noticed that one of the front struts is pissing out oil and doesnt spring back as it should. so im guessing the other side is gonna go soon too.
Also ive found the handling to be very different to alex's car which is identical except that he has KYB struts which are still stiff and have have had about the same abuse as mine. So now im up for new suspension all round. This time im going to spend the extra to get KYB's for sure.
So there ya go.
