If you have lifter tick in a 2.9 you need more than just lifters, you need cam bearings too. Cam bearings means the engine comes out.
Don't buy a whole donor vehicle for a 4.0 swap. Just go to the pick'n'pull and get an engine a harness and a computer.
A4LD is A4LD is garbage, so that's not too much of a concern. The 2.9 unit should hold up to the 4.0 as well as a 4.0 one would. The reason you see a rash of failures of 2.9 A4LDs behind 4.0s is the 2.9 didn't have the guts to finish breaking the trans.
This was my point, replacing one thing leads to another, more money, more time, and in the end you still have an underpowered crappy little engine that you wasted a few hundred bucks on.
