I shall be mainly ripping the back end of the other halfs Boxster S apart to get the rear wheel bearings out.
True to law of sod last week we decided to take her car on hols, yesterday the rear wheel bearings started humming.
So bearings bought and the world will have to put up with a grumpy me as for the next few nights I will be changing them.
At least while I'm in there I may as well do the gearbox oil too.
Bloody cars.

Just to add to my somewhat short post above.
It's not a small job, not least because of finding other things wrong, in this case a pair of split cv boots that only appeared split when jacked right up.
So drive shafts off, usual bottom ball joint fun, then the mother of all drop links, ended up having to cut it off as it just wouldn't release, must be the original had totally welded in to the alloy upright (interestingly made by brembo in Italy like the brakes). So bearing pushed out and the stub of drop link pushed out. I'm expecting the other side to be as bad.
But it is perfectly doable.
At least once it's done it will have 4 new cv boots, 2 new drop links, 2 new bearings. So basically everything big will be done. I'm also changing the gearbox oil at the same time. Which thanks to the worlds most stupid under tray design isn't the easy job it should be.
Then it's going a thousand miles down to Cavalaire on Thursday!

As above.
Put it this way last nights job would have taken an OPC about the same length of time as me, but they would also have wanted to replace the perfectly servicable rear brakes including handbrake and cables that will happily last to the next service or beyond.
So circa 4-5 hours of labour to dismantle plus probably 1.5-2 to reassemble at OPC rates?? I think not.
Parts cost is around £200, so the jobs costing £200, I reckon I wouldn't see much change from a grand from an OPC. Plus I get to see what else may be getting tired and have the money spare to do it.

Quick update for anyone looking to do the job.
Wheel bearings arrived yesterday, so last night got the other side upright off, swine of a job, the drop link came out far easier (I had to cut the O/S out) but it just wouldn't release off the bottom arm, the drive shaft wouldn't get out of the way enough everything was just a pain, ended up dropping the bottom arm off totally and then it all came free, turns out at some point someone has slightly bent the thread on the bottom ball joint. It's not serious and I'm tempted to leave it as it won't be detrimental, at the same time were driving 2000 miles in a few days I'm seriously tempted to change it for peace of mind.
So the wheel bearings....
Drivers side the drive flange popped straight out, knocked the other side inner race out with a hammer and then pushed out the outer race without much difficulty. Cleaned up the casting with a little wet and dry and applied a little bit of wd to lube it's way in and it pressed in without much difficulty.
The Passenger side though was a pain, the drive flange had rusted in to the inner race and would not push out, it took about 10 mins to break the seal and push it out, then knock the inner race out and push the outer race out of the upright, all this was achievable with little more than some large sockets and hammer and chisel. Refitting the new bearing was a little harder as I forgot to clean the casting but it went in cleanly.
Refitted both bearing retainers now as I'm guaranteed to forget otherwise.
Now I had to get the old inner races off the drive flanges. One side it just drifted off with care, but the passenger side (the one everything was tight on) it would just not budge. I ended up having to resort to a thin slitting disk in the angle grinder and cut a groove in the bearing race and then hammer a chisel in to the groove to split the very hard steel. It split and slid straight off, much better than risking deforming the flange beating it off.
Started to disassemble the drive shafts ready for the new CV boots, so tonights job is to fit the new CVs, press the drive flanges in to the hubs, start reassembling the suspension then change the gearbox oil. Tomorrow finish the job off and take it for a short drive to make sure the problems gone away, then come back check everything is as it should be and then go for a fast thrash out to bed everything in and then check and retighten everything, then Sunday hopefully get the car ready for it's journey.
Otherwise I'm back to plan A and taking the ratty MX5.

Nope...
OPC's were invented so people could use the phrase "a fool and his money are easily parted"
Or perhaps to provide a service to that section of society who just enjoy driving a great (and newer) car without having to worry about the oily bits or the cost... most of the "foolish" customers at my OPC seem to go on a lot of skiing holidays... OPC's were invented so people could use the phrase "a fool and his money are easily parted"
All a matter of perspective...
