  • Front Spindle Thrust bearing
  • I have to replace the front "thrust Bearing" on the spindle. I am not sure which way is up or down. Does it matter? Please help

  • Its been a long time since I did that but IIRC thay is a tapered roller bearing. The cup is pressed into the bottom of the knee and the cone slides on to the spindle.

  • Re: Front Spindle Thrust bearing
  • Who has a tapered roller bearing for sale? I have only gotten the ball bearings from Just 8Ns. I would prefer the tapered roller bearings.

  • Re: Front Spindle Thrust bearing
  • It was close to 20 years ago and I am sure whatever I got came from Just8N's. I am not positive but I don't remember a ball bearing. Given the elapsed time I could easily be mistaken.

  • Re: Front Spindle Thrust bearing
  • Newbie on here so dont put much weight in my comments...but I just removed them from my 8N yesterday and the open end was down. Seemed to make sense as the upper side should stay locked in the spindle housing??
    Couldnt resist commenting as all I have done is post questions, never had an answer for someone (and it could be wrong)

  • Re: Front Spindle Thrust bearing
  • That is correct for thrust bearings.

  • open side to the oil. In this case, the grease.

    Unless it's sealed, then it doesn't matter.

  • Re: Front Spindle Thrust bearing
  • Thanks. Why didn't I think of that. It's not sealed so I will put the open side up toward the grease fitting.

  • Re: Front Spindle Thrust bearing
  • Look at a thrust bearing and determine what part has to move and what part stays stationary. Orient it to the spindle accordingly. You do not have a moving part against a stationery part.

  • Re: Front Spindle Thrust bearing confusion
  • Thanks but now I am confused. The spindle is the moving or rotating part and is on the bottom and the front-axle-knee (which holds the spindle) is stationary (and would be on top). That means that the open (moving) part of the bearing should go down toward the rotating spindle. Another person suggests that the open end of the bearing should be toward the top or the side toward the grease-fitting. This is the opposite.
