How do you replace drive shaft in TR magna?

If you are referring to the cv shafts to the front wheels, as follows: drain the box oil, remove split pin in the outer hub nut and loosen the big 30mm nut with a breaker bar. jack up front of car, remove wheels. undo caliper, hang out of the way. undo the 2 strut bolts from the hub. undo the lower hub ball joint and the steer rack ball joint. this is done by undoing the nut, then whack the cast lug where the tapered pin goes thru on the side with a heavy hammer- this will deform the lug by a few molecules, just enough so that the pin pops free. now get a prybar between the inner end of the cv and the gearbox housing, and with a quick flicking motion, pop out the cv. CHANGE THE SEAL where the cv goes into the box or your new oil will fall out on the ground. I,ve just done 2 gearboxes last week, this is the easiest way. seals cost about 50$ au for two. good luck, justin.
