servicing king pin bearings re-grease or only replace

[Fireblade]

hi,
i have a 2008 gu wagon CRD 190,000km
i just recently re-greased the front wheel bearings and got me thinking should i do the king pin bearings as well or at they something that dont get service and only get replaced?
also what about rear wheel bearings? are they something i should be re-greasing?

i know the service interval for front wheel bearing re pack is 40,000km but i cant see any interval for other bearings like rear or kingpin.

thanks

Yeah you could do that, they would welcome the grease for sure. Do them one at a time and leave them on the pin and repack and refit them. The rear are pressed on and it you go to the trouble of removing an axle then its worth trying to squeeze some grease in there for sure.

Your front end is probably due a rebuild to be honest mate.

The rear bearings are hard to get grease into as they are pressed onto the axle. But if the rear axles are coming out then definitely try to push some grease into them.

Get a needle attachment for the grease gun. Will make light work of re greasing the rear bearings.

I do have a swivel hub rebuild kit ready to go but I’m held up on the whole pre load to the king pin bearings.
I don’t think I can just use the same shims again and that may not be right for the fresh bearings

At this stage the the car drives well no wobbles but pulls slight left waiting for a wheel alignment and that might suggest offset king pins, that what the tyre shops says.. so for not I’ll wait for that. I’d hate to put new ones in and have to swap em for offset ones

Yeah they’re brilliant those needle points. I even made my own using a grease nipple, an air line fitting and a piece of 1/8th air line. So it’s slightly larger than the needle point, quicker greasing and it’s also flexible. And still small enough to get in between the bearing rollers.

thanks everyone next chance i get ill pull each kingpin plate out one at a time and clean them off and use one of these needles to re-grease them.
will the bearing need to go back in at the same spot? meaning is i pull the plate out and the bearing gets spun 90-180 degrees and put back in would that be bad?
im thinking if this happened the bearing would be contacting a new area on the race.

Just remove teh cap and leave the bearing on teh cap. You wont need to use a needle packer for the king pin bearings. If you ahve ever repacked a bearing using your hand then use that technique, will work perfectly. Just make sure the king pins go back where they came from, if your doing them one at a time you cant get it wrong.

that needle grease packer will really only become handy for the pressed in rear wheel bearings as you can only get to the face of the bearings.
