You don't say how many miles - but assuming it is over 100K you need struts! Also check the setting of your ride control if you have it. I've got a 2007 V8 I bought in 2011 for about $35K. The GX470 supposedly is the best 4 wheel drive because it's on a 4-Runner frame (the best 4 wheel drive vehicle) Michelin tires are the best I've had on it, however the last time I went with some new Good Years that are a close at 2/3rds the price of Michelins.
