Toyotas aren't >perfect either. I've owned two Toyota trucks and two Toyota Celicas (all mid-to-late '70s models, 20R motors). I only ever replaced one timing chain, and that was only because I was already installing a new rally cam and some other stuff. Never had a pinion fail on any of the three, and two of the vehicles had over 200k on 'em. What *did* seem to fail with some regularity was stuff like voltage regulators, water pumps and alternators. Clutches never seemed to last all that long either. But the single biggest weakness on those 20R motors was the factory carburetion. A single Webber downdraft carb (and K&N air cleaner) would work flawlessly and make you think you were driving a whole different vehicle! (Even if that was the only performance change you made). Those old Celicas had two (inline) driveshafts, and I never even replaced a single u-joint. My buddy had an '81 Toyota pick-up with the 22R and he never had any trouble with his either. Well, except for the time we put big dune buggy tires on the back and took it to Sand Lake... his rear fender wells got toasted pretty good in short order. ;-> Plus we got stuck several times before we could get back to the parking lot. You had to go slow to prevent the tires from rubbing, but without momentum the thing we could stuck real easy. It was just a bad idea in general. I agree though, no vehicle is perfect.

It's just sometimes Toyota owners seem to view the world through very rosey glasses. :) I'm not knocking them... in general they are very good vehicles. but I'm not sure their reputation doesn't far exceed reality.
From: Dean H. on 4 Jun 2007 09:25 >> blowing pinion seals >>u-joint. So, for this week's Chevy quiz: I've noticed a ticking noise which varies directly with road speed (independant of engine speed). I can only hear it at low speeds if I'm next to a building or some other sound-reflecting object. U-joint seems like the most probable culprit, although it all seemed plenty tight last weekend with a very casual inspection. Maybe my pencil arms don't generate the same kind of forces a 305 does. I'm not sure it's any more of a problem than a little ticking noise, so I'm not panicked. I think it's been there a while and I'm just listening a little harder now; paying a bit more attention. Maybe I'll drop some fresh oil in the diff. There is that magic time in a vehicle's life where stuff starts coming due. For many, it's a good time to sell and let somebody else have what Chip calls the second half of the vehicle. I think I'll ride it out with this one. Okay, enough rain now.
