My z has been pulling to the left ever since I got it and it was ignored until now. One some roads it'll pull left. Sometimes it doen't pull at all and drives nicely. I've checked all bushings in the front and they all checks out. Now just checked the rear and the wheel has significant play if I shake them at 12 and 6 o'clock positions. No horizontal play. All other bushings appear good. Upon further inspection tie tods seem to have play on them. Could this cause pulling? Also how difficult is it to replace them? Some search on the net and it looks like it may be a pita with 17mm nut. Thanks in advance
