Hi All
Yes, I’m onto the front now. Looking for any input people feel is needed. Am planning on replacing every bearing and seal in the front. Thanks for the help the other day in helping me “ re do the back end”, took it for a drive and there were no squeals and the wheels stayed on, so fingers crossed. Front end,MMM,
where to start? The grease seems runny, which is what I was expecting as the front diff oil discoloured quickly. Bearings were ok, unlike the rear. Will replace them and the king pin + the spindle bearing. 1st question, how do I get that spindle bearing out? See photo, don’t wish to butcher the brass part to replace it.
How to get the king pin bearings out? See photo of top one, the top part will easily come out so far but no further? Re the bottom arm that attaches to the steering, has anyone bought the SST needed to push this bolt out? Seems
well stuck. Re the freewheeling hubs, I have read that these should just have a light coat of grease, yet one was packed quite full and still worked ok? Re, repacking the steering knuckle, the general consensus is that it should be about 2/3rd’ full, what do think? I have pumped LMM grease in through the top bolt once, it was
grey, same colour as was in there it would seem, or maybe that was the diff oil mixing?
Interesting the bearing grease was all
grey, a bit strange, any thoughts?
Enough for now.
Cheers Lyndon
ps. how do I grease that last part shown? Take that clip off?

It has been discussed at length on here before but basically the hubs on a 4wd do not get hot enough in normal operation to "melt" the bearing grease and allow it to flow into the bearings and lubricate them correctly.
I used to use HTB but I also used to replace the bearings regularly ;-))
A mechanic mate offered to wash all the hubs out for me at his workshop for me years ago and when he returned the hubs and bearings he said to me that the bearings were
well worn and asked how many k's it had done. I replied 40k and he then asked what grease are you using. My reply HTB!
His reply was WRONG! as per above use either a multipurpose grease or a specific "clingy" grease like Castrol APX which is a blue colour.
I have since (for the last 25 years) used it in everything involving bearings and have not had to replace any bearings on the 4wd or the trailers.
The camper used to need new bearings after every 3 week trip using HTB, since using the APX I've never replaced them and only repack once in a blue moon (5 years at last count).
The Toyota workshop manual used to say to use multipurpose grease on the earlier 4wd's too.
