He hit the nail on the head re: water and aftermarket shoes that I thought was suspiciously too cheap when I bought them and was raining *hard* all day friday. I didn't had to remove the wheels - 5 spoke aluminum with plenty of space to hit between spokes - just lifted wheel on the jack and on the third tap it released. Will look for into getting oem shoes, they last at least for 8 years after alll... Thank you so much! -- T

But stay away from the cheapo aftermarket ones. Move up in the line and get the better quality, and therefore more expensive, shoes and you will also get good service.

Even though decent aftermarket /is/ available, I'd rather have eight years of the certain reliability you get from OEM shoes. I was also going to ask if you had aftermarket shoes, but I've been dumped-on too many times for suggesting that aftermarket may be inferior to OEM. So I held off. -- Tegger

So I held off. The deal around here for Toyotas in general is either very crappy aftermarket parts or OEM with a hard to understand price policy. Some parts are cheaper than aftermarket, some are much more expensive. I'm in the market for shocks. OEM lasted 80k miles and are still usable, not too bad but not good either. A pair of rear OEM costs almost double than the set of four aftermarkets, but since I have no plans to sell this car anytime soon, I just might fork out the cash for what dealer wants for oem. Honestly, not only Toyotas, but in general, aftermarket parts (usually made in China, nothing against them, great country, been there and really enjoyed) are of much inferior quality and in the long run they tend to get more expensive... -- T |
