I recently got four new tyres from a shop and they said they wouldn’t be able to do an alignment until I got my tie rods fixed. They said they can’t do any alignment work if there’s any play in the tie rods. Is this something I can wait a couple weeks for or should I worry about it ASAP since I just got new tyres?

2015 Nissan Altima 2.5s.

Car shakes when going above 60. I was driving on the freeway going 70 the other day and my passenger seat was shaking like a tambourine. There are no sounds with it. It doesn’t happen when going slow, except sometimes after I’ve been driving awhile. Was hoping somebody could help diagnose or give me direction for the cheapest / easiest way to diagnose myself?

My assumptions is may be a tie rod, tire imbalance or something with my cv axel. TIA
