By counting threads/measuring carefully can tie rods be replaced without realignment?

By counting threads/measuring carefully can tie rods be replaced without realignment? This is on my 85 300D W123. If I take the old tie rods and assuming they are the same configuration as the new Moog replacements, can I swap in the new ones by a combination of measuring and counting threads carefully on the adjusting nuts?

Don't worry, I'm not that Cheap, I just want to wait for my new tires before I realign........

yes, but if you get 2 straight, square bars held horizontally to the lower inside of the 2 front tires, you can measure front and back and get a real good idea of what the toe in actually is.

Several different mechanics have counted the threads when replacing tie-rods in the past on my car, and it NEVER worked. I should add that it was always my idea, not theirs. They always advised me against it, even though they themselves were not equipped to do wheel alignment. I subsequently always needed a wheel alignment done. Of course it may have been the case that the wheel alignment would have been required even before the repair, but why chance it? Do a proper alignment.

How can you tell how much extra length a worn ball joint will add?

You're right to get an alignment with a spreader bar and is familiar with MB's. If the car is tracking fairly well by the thread counting method it sounds you're okay until you get it professionally aligned. Once you have toe in, caster & camber on the money it makes a world of difference and is well worth the money. You'll get many more miles out of your tires too. Like twalgamuth said, you might get lucky & you might not in the short term.

IF you are planning on getting new tires soon, then I wouldn't worry about getting an alignment, measuring and counting will sufice. But if you wan't to get the most out of the tire currently on the car before getting new ones then I would get an alignment.
Will new tires really necessitate a new alignment?
