Installation was fairly easy but the gaskets are different from the original gaskets that I removed from my 2005 Sienna. Basically, two grommets are fitted to either side of the attachment point (one inside, one outside), which are then each held in place with a metal washer and nut on the inside. Another thing to consider is that while my original bolts were 17mm, here were 19mm bolts, meaning I had to ask a neighbor for an extra key during installation (my set went to 18). I've been using them for about a week now. and I can feel a definite improvement over my original ones (which admittedly leaked). Update, about 2 years later - one of the two I installed was shot through, completely rusted, affected handling and was making muffled noises.
