Also replaced a control arm with a new volvo part (ball joint bad). In theory any of these parts might not be identical. I'm holding off because I want to replace the other control arm. I just might have to do 500 miles this weekend. Car seems to drive OK. Actually I replaced a wheel bearing too, so it drives great. Quiet.

So I hope my tires survive a 500 mile trip. But maybe a volvo mechanic would have experiences of changing tie rods and finding alighment unchanged or greatly changed.

The camber may have shifted slightly with the new CA but it can be a bit tricky trying to adjust it DYI in your garage.

You can, however, do a ballpark toe-in measurement and adjustment following the tie rod replacement.

If you shoot for about 1/32" of toe-in (the span at the front sides of the wheels is 1/32" less than the span across the back sides of the wheels) you should be OK for a 500 mile trip. Just make sure you and your assistant use the same reference points on the tire treads when measuring both leading side and trailing side.

BTW, when adjusting the toe-in you can also correct an off-center steering wheel at the same time. Example: When driving straight down the road, your steering wheel is turned slightly to the left. So you measure the toe and you find it has too much toe-in. The fix is to shorten the LH tie rod which turns the LH wheel outward which forces you to turn the steering wheel slightly to the right. So regardless of whether you have too much or too little toe-in, the correct fix is crank one of the wheels toward the side that the steering wheel was pointing.

Hopefully this was understandable and maybe some help to you.

You can minimize the impact on the alignment by marking the threads/counting the turns when replacing tie rods, but in all likelihood an alignment would still be a good idea (especially if it has had an alignment previously that may have made some adjustment for wear on the control arm/tie rods/wheel bearing). You can probably get by for a while, but in the long run the alignment costs less than a tire, and you might end up needing to replace two...
