Hey there all,
I recently bought a landcruiser hj47. all original with 168 thou on the clock. This particular vehicle had been sitting around for some time before I got my hands on it. After purchase, I changed all the running gear lubricants and engine oil, etc. The front diff dropped oil that was dark
grey in colour. mmmm. I hope nothing serious. I could'nt see any metal fragments, thankfully. Anyway, I read in the owners manual under ' running in procedures' That you could run the vehicle in H2 with the front wheel hubs locked to run in the front drive components. I would like to do this for a while to lubricate the front drive components and wash all the rest of the old oil before dropping and replacing the oil again As I don't intend to do any proper 4wdriving in the immediate future. I will not proceed until I am sure that it's O.K to do this.
What do you think?

Jim, have seen this
grey oil, even in later models, think it may be a mix of oil, water and grease out of kingpins. Think water can readily get past swivel hub seals, thus making oil that
grey colour. Just make sure you pump some grease into the swivel hubs(for king pin brgs) every second oil change. The 47's are a bit weak in king pin mounting studs, so bearings need plenty of grease to prevent them collapsing. It's an adrenaline rush when they do!!!!
Sounds like you've got a smig ute, especially with those k's. Need to run ute in H2 with hubs licked, for 500kms/month, to keep king pins lubricated, suppose it would depend on how many k's you did in it per month. Hooroo...

Thanks Guys,
Bob, Now that you mentioned water getting past the swivel hubs, when I greased these, there was hardly any Grease in these. Especially the right side.
It's all maintenance! Is'nt It?
It sounds like you had a 'fun' time because of those king pin mounting studs. Am I right to assume that you had this experience?

Jim, I stand corrected, so it's 16/month, ah
well, haven't read a 47 manual for over 15 years.
Had a collapse of king pin brgs on at least 2 occasions, once at 80 clicks. Wheels just splayed outwards and we stopped fairly abruptly. Another time the brgs collapsed but as we were towing a van over station roads, didn't break any studs.
The bigger studs on these later models was way overdue. Hooroo...
