Hi,
Yes I did my front subframe. TD6!. from memory quite easy. Both driveshafts out. exhaust off. I hung engine with engine hoist. two engine mount bolts off. disconnect steering pipes from steering rack. then undo 4 subframe bolts and it will come out with rack on. once out remove rack. fit to new subframe then back up. bolts in. connect rack to steering colum. connect steering pipes.
What I did learn is dont tighten bushes until wheels are on the ground then tighten, or thew bushes will grind away making an awful noise.
