George,

If you are going to replace everything (thrust arms and lower control arms), I wouldn't worry about a balljoint tool. On each side, remove the outer tie-rod, unbolt the thrust arm and control arm from the frame, then unbolt the steering arm from the bottom of the strut. You should now have in your hands a steering arm with two control arms attached by their balljoints. Mount the steering arm in a vice and whack the #$%^ out of the balljoints with a pickle fork (or use an air chisel). Since you are replacing the arms anyway, it doesn't matter if you destroy the balljoint boots. This is a WHOLE lot easier than trying to disconnect everything on your back.

Incidentally, it is nice to have air tools but I believe that a garage would be even better. After working on the car, I always end up with gravel rash!

Thanks for the advice Alex. You are right, I have
to become more of a legitimate home mechanic and
buy some air tools. Also, thanks for the heads
up on the ball joint puller from Bav Auto. I
thought maybe one size fit all....guess not. I want to tackle my front suspension and replace everything and add a modest drop to the car by adding H&R springs as Carlos did. I look forward to the challange.
As far as the heater core goes, its quite a job
but eminently doable. I couldn't have done it
without the indispensible help of people on this
board...particularly long lost Stefan who as you
may recall went in not once but twice...he should be knighted!...and to create a comprehensive website to share with everybody in his second language no less...he's a pretty remarkable guy. I downloaded all I could find about heatercore
replacement...many have posted...thanks JFD for
your advice about getting the center consile
wood facia off..if you pull wrong you can break
off the bottom clips...stuff like that... every- thing is there. I do have a tip for you so if you get ready to do it give me a shout. My core didn't look too bad...O-rings were beat as expected. You probably are aware that BMW clearly was running too much cooling system pressure....hence the radiator cap recall which
undoubtly contributed to premature 0-ring failure....not to mention intermittent heater core/plastic piping failure.... I'll leave it there. I took the precaution and replaced the core, plastic pipes and O-rings. You don't want to go back in there anytime soon and
of course use original BMW parts. I've taken my
time and refurbished and cleaned everything before
reassembly...I'm pretty meticulous.
Enough rambling...wish you the best in the New
Year!
George
