I just had a 4-wheel alignment on my 2002 FWD RX300. I think it has been about 4 years and 45,000 miles since the last one. Everything was in spec before and after the alighment (you need the alignment to know you didn't need the alignment). There was somebody a few weeks ago who wanted to know how often you need an alignment.

I went to a shop recommended on the NELOC forum, PTuning in Manasas VA. They had a $99 special. It was interesting to see how much more advanced the equipment for doing alignments has become. I think they had one by Hofmann? I guess my hand alignment gauge must be an antique!

 

Yup,I believe that was me.I had mine done in january (just the front alignment)and it was off slightly.We just took a trip to Wild Wood Crest in NJ.And Rt.206 was full of what I like to call (speed bumps.)I hit one so bad,it knocked the power cord out of my gps unit.Just love the good ole North/East,but these are some of the reasons I suspect you should get it checked at least once a year/15,000 miles.
