alright guys im in the market for new wheel bearings (all 4) and i see i have the option of standard ball or tapered bearings.

i understand


ball bearings - can pit fairly easily and therefore dont last as long but that they are smoother and cause less friction.

tapered bearings - are more rugged and can handle higher loads/stress but they introduce more friction into the mix than ball bearings...


if im wrong anywhere please feel free to correct my mistake :)

im looking for best cost/best performance i dont mind spending a little more for the tapered ones but i want to know if its worth it. anyone on here have tapered wheel bearings?

so pros and cons of both if you guys could. much appreciated

I have never seen ball bearing wheel bearings. They would reqiure a seperate thrust bearing or thrust surface unlike the tapered roller type.

I've never replaced the bearings, but with our cars being FWD, I would assume they are sealed. I don't have my WSM in front me, so I can't be for sure :shrug:

No. Ball bearing races are not designed to survive under thrust loading. They require a sepperate bearing because there is so little surface area on the sides of the races. tapered roller bearings are designed to work well under compound forces.

I have never worked on any car with ball bearings in the hubs. They have all been tapered roller types.

The bearings in these cars are tapered rollers, 2 back to back in the one shell.

The good thing about that design is that the pre load is set, and cant be changed, the bad thing, if you disassemble the hub you destroy the bearing in the process.

They have a long life compared to conventional tapered rollers and ball bearings.

I did have a car that had ball bearings in the hubs....but it was light, i.e 670kg, 1475lb.....and they didnt last all that long but are easy to change.

I doubt there would be room for a suitably sized ball bearing in the hubs on our cars....

I am doing a whole pile of wheel bearings atm, I might duck out the back and take some photos.

my gt-four has ball bearing wheel bearings. They each have two rows of ball bearings. Its far from a light car stock, around 3200-3300lbs. Mine probably weighs in at just under 3k. I've killed 3 so far. Nothing like pulling the rotor off and being greeted by two dozen little balls rolling all over the driveway
