Needless to say, we were well on our way before I really noticed it. My first thought was wheel bearing. We continued the trip, and 500 miles later we got home. No grinding, no additional noise, but I was able to lift the truck and sure enough there's a bit of play in the wheel. It turns out the passenger side is the culprit. I could slightly feel it when sitting in the passenger seat while she drove. Anyway, I am ordering parts tomorrow, but wanted to ask for some thoughts. Do I need to replace both sides at the same time (is the other just waiting to fail)? Truck has 110k miles. Also, is it safe to drive short distances until next weekend after the parts arrive and I can replace? I know the right answer is no, but it would be easier if she could drive this to genuine Toyota parts, but I don't think they sell the full hub and bearing assembly? Can I replace just the bearing, or will that require pressing the bearing into the hub? I've read some threads here, and watched a couple of videos. I'm wondering what all parts I need to replace? Hub, bearing, seal between hub and bearing, small seal behind the hub? I just replaced the front oil pump seal and a few other items on my 3rz tacoma, I was hoping not to tackle another project so soon. Is this something I should let a mechanic handle? Any thoughts on cost for a shop to perform the work? Any thoughts are greatly appreciated? Thanks
