Thanks for the tip.
The tie rod ends are cheaper (approx. $35 each) and the rest of the assembly (approx $70 each) is still in good condition, so I was thinking of just doing the ends.

Napa has it listed as:
1992 Mercedes-Benz 400E
Comments: w/ Right Hand Threads
Per Car Qty: 2
So both left and right would have right hand threads, Is this correct?
