I have a 2011 LTD 2 wheel drive with 62000 miles. How long should I expect the struts/shocks to last? Which brand do any of you run/recommend?
We just put new tires on it (Nitto Q421, 275/55R20) and even after the RoadForce balance there is a bit of a wobble as you go past 55mph. Thinking it may possibly be the shocks.
Any suggestions?

I am not even close to replacing my 4runner's struts, but I can tell you that on my '03 Avalon the original struts were all blown at 25,000 miles. When I got around to replacing them at 30k I could easily compress them by hand - they offered no resistance at all.

Now this was all city/urban driving on the rough streets of Albuquerque, but since then I haven't put much faith in oem toyota struts lasting too long.

As for the wobble, I had that too in the same car. It was warped brake rotors. It was also not noticeable until highway speeds.

Hope that helps. I don't have any opinions about which brand of strut you should look to for replacements. There's lots of info about that here on the site though. Bilstien seems to be a perennial favorite.
