Hi Guys
I'm in desperate need of some advice. I have a 2003 toyota corolla 1.6GLS with 140000KM on the clock and I replaced my wheel bearings 3 times. The first 2 times, the bearings did not last for more than 3000KM's. I have to admit I bought cheap Chinese bearings.
The 3rd time which was about 1000KM's ago was replaced with original wheel bearings on both sides. The noise of the old bearings were so bad that driving at speeds of 80-100KM/Hr produce the following sound. A grinding dragging sound and I would best describe it like a piece of wood being dragged on a tarred floor.
Today, while driving very slow (10KM/H), I found that turning both left and right would produce the very similar sound as described above. And this frustrates me because I've spent money replacing the bearing 3 times and they don't last more than 3000KM's. My question is could it be the bearing this time or is it something totally unrelated?
I must also mention my left side CV joints has failed and my car continuously makes a clicking sound when turning right. Hopefully this will be repaired by the end of this month.
Guys, I'd be so grateful for any assistance and advice. This problem has been recurring for the past 8 months and this time I spent money on good parts to find this coming back to haunt me.
Thanks
T

Stay with a good quality bearing and have the hubs replaced this time as well. The hub/wheel bearing when assembled and the axle nut torqued to spec, is what sets the preload on the bearing. If during the first failure (bearing spun) or during the replacement of the first bearing, the hub became damaged; that’ll be the problem. Some techs will pound on the hub, during disassembly which will mushroom it and change the over-all length of the hub’s arbor. This mushrooming will shorten the length of the arbor, which in turn will cause the bearing to run to tight when the axle nut is torqued to the hub/bearing assembly. And I’m not talking about getting your tape measure out type of measurement but micrometer close measurements.
As for the clicking CV; if you mean the original axle, then replace it. If you mean a replacement is clicking replace it again; making sure that it is of a quality remanufactured. There are some really cheap “new” aftermarket axles out there now and there’s a reason why they’re so cheap. The machining tolerances are not the best and they may have cut costs by shortening the race where the ball bearings run; causing the clicking during turns.
