Brian,

47 isn't too bad. The archives say that parts store tie rod ends will run in the nieghborhood of 80 bucks. When I needed them, ABLinn had the rights for 15 a piece but no lefts. I had to get the left from Memphis for around 30 I think . AB may have both in stock now.

I don't know how much play is acceptable but I'd reckon that you don't want any. They're supposed to be tight with zero play. If all 4 move .050", by the time you get the the left tire, you have .200" total play. Thanks to geometry, the measured play increases as you move farther along the radius of the tire.

You should have a pickle fork or somthing similar to change them but I haven't seen one large enough to do ours at the parts store. If you want to be a barbarian like me, you loosen the tie rod end nuts and whack the side of the steering arm by the rod end with a single jack. After a few hits it'll usually pop loose.
