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?

the picture of the light
grey spindle looks suspiciously like moisture mixed with the grease.
check those big outer seals held on with all the bolts as they may need replacing as
well as the inner seal. Be sure to clean up the surfaces that the seals run on with wet and dry and fill the lips on all seals with grease before reassembly.
Don't use HTB grease on the bearings, use APX or similar.

AHHHH @#$%, have already done the rear with HT Bearing grease and have packed one front hub with it. Have not yet put that back on. Any reason it's no good?

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.

Also called trunion bearings. The grease is contaminated by diff oil...that makes it go
grey. Make sure you replace the axle seals. Wheel bearings get bearing grease...I prefer to use Castrol boating grease..it's more tack and stick better. The trunion bearings, steering knuckles, and drive shafts get a molybond grease like Castrol LMN....it's
grey in colour.
I'll re-read your post later today to see if I've missed something.

It seems to depend on who I talk to as to what story I get in regards to the type of grease.
Thanks for your input.

Lyndon, I've used HTB grease for 20 years on Landcruisers and never replaced bearings - I reckon the hubs get hot enough for it to work as intended. I wouldn't use it in a trailer because the hubs usually don't get hot.
Having said that I'm going to change over to the Valvoline Valplex EP on the Landcruiser - blue coloured grease.
And you need the black LMM for the svivel hubs etc.
Another word of advice is that after replacing the rear bearings, you'll need to go back in a few thousand K's and
check for play and readjust. To do this, you have to remove the rear axle shafts, otherwise you won't feel any play. If you allow play to remain, the rear axle studs can shear.

Hi Phil
Oh what joy! I get to pull the rear axles out again, YEAH. The bearings are in for a real experiment in regards to grease, the back end has been packed with HT Castrol grease, the right front bearing is packed with the same, both kingpins/tunion and hubs + left hand front bearing are getting packed with that blue stuff. I guess it will be a true experiment? Thanks for the advise re the rear axles, I hadn’t thought of having to take out the axles to feel for play, makes sense though.
Cheers Lyndon

All will be good, Lyndon!
The 70series Landcruisers last forever. They are so popular here that a couple of 3 year old HDJ78's just like yours went for $45k at the Government Auction recently. My 79series is going to be a keeper - it was better than anything I can get new at the moment. So like you, I'll be up to the elbows in grease next month - its done 150,000 now, so it will get those slotted rotors finally put in and will get everything serviced including new timing belt etc.
The breaking of axle studs (the ones that have the cone washers on them) has been relatively common in the earlier LandCruisers with 8mm studs. Toyota upgraded them to 10mm studs on our vehicles to reduce the chance of this happening. But it appears that the breakages were more common after rear wheel bearing servicing and excess play is the cause. Most people don't realise that the shafts need to be out to
check for play on the rear. I replaced the wheel bearings on my daughter's 80series 6 months ago and rechecked for play last month and all needed adjusting. Its something that's worth doing after replacing bearings, but not necessary after regreasing old bearings.
I feel for you not having a shed. We moved to a new place that has a great double garage to work in, with a glossy floor that's easy to slide on and keep clean, but I have to remove both cars to use it for tinkering. And the neighbours are a bit deaf and tolerate hammering pretty
well :-))
Cheers
Phil

I dunno, but when i have seen mechanics changing axles and over hauling front ends, i have never seen them use more then one type of grease. Never seen them use anything different for bearings, hubs, etc. Just use good quality grease and all will be fine they tell me. Usually Mobil grease too.

Hi Boss,
Workshops like to minimise the number of greases they carry.
"Just using one grease in everything" is fine, but not for the Birfields (CV) - they need moly grease.
If you want to use the same grease for everything else, you need to be selective - something like Valvoline Valplex EP is OK for wheel bearings, chassis, universal joints and
suspension. I would be surprised if any workshop would not use moly for Birfields on a Landcruiser.

Once you get all these wheel bearings sorted, I don't want to hear of you
parking it in salt water over night ever again!!!

Hi Chris
Thanks for the letting the world know ! Who is going to buy my "pre loved" car now? Just joking all’s good. Fortunately those four days under the car with the hose and pressure washer at the Walkabout have meant that there is no rust to be seen. As the time frame for the longevity of the vehicle set out by Bernadette at the time of purchase was considerable, many of the formites will be suffering old timers by the time it is up for sale, including quite possibly myself! It’s was about time to re educate myself with how to re build both ends anyway. The worst part is trying to do the work where we live! Resort style living has it’s bonuses, this is not one of them! You don’t get to lay anything out in order, it all just gets stuffed back into a box every time I have to go upstairs, and then there is the NO BANGING rule! AHH, if there is a death in Cullen Bay in the next week it was probably me killing the manager!
In the unlikely event that you will be around
Roper Bar at
Easter let us know. Our Barra boat arrives on the train this week so we will be down there for a fortnight reeling them in!
How are the plans for the big move going? I suspect
John will be wondering in how many countries he has to advertise to replace you two? Due to the “ communist pay system” he may
well be best served trying the eastern bloc country’s first ?
Well of downstairs to get covered in grease again.
Cheers Lyndon
