Frame is rusting apart rear lower trailing arm section has already been patched by previous owner upper trailing arm connection point to frame crossmember has perished due to rust if the other side breaks the rear axle can flex excessively causing control problems Toyota’s service campaign for other trucks should not have omitted the 4runner which shares many identical design characteristics.
I purchased this vehicle used from a dealer in 2014 with low miles on it and it appeared to be in great shape. The undercarriage was sprayed with what I thought was a coating to protect against rust. I realize now the dealer was probably trying to hide the rust problems. The coating flaked off a short time later and ever since, I too have been plagued by the frame and other component rust problems. Had to replace the exhaust, running boards, sway bar and several other things that all rusted off on the undercarriage. My skid plates are about to fall off next. Just had my brakes replaced and the shop noticed a couple areas where frame now has holes through it and says it likely won't pass state inspection which will be coming due soon. The rust problems with these 4runners seems like a big problem that Toyota should address. I'm going to have to put a bunch more money into fixing this vehicle or be left with a worthless piece of junk I can't drive and will be taking a big loss on.
