Sienna wheel bearing woes
 Owned Sienna for 4+ years now. Only 120,000 kms on vehicle and both front and rear bearings simply worn out. Very expensive to replace, as both bearings and hubs replaced same time. ($ thousands). No help from Toyota to date, but I continue to ask. Tires were an issue, but they did replace under recall. All toyota AWD vans seem to chew the tires off their rims! We had AWD Previa before and same problem with tires. Power window fell off track and over $400.00 to replace. This is an extremely expensive van to buy, and maintain. Paid over 45,000 taxes in, and still forking out thousands to keep it on road after only 4 years. Most parts are only available through dealer.
