Boydie Posted November 5, 2015 Share Posted November 5, 2015 Has anyone drilled and tapped and put a grease nipple into these hubs? I'm looking at the official Land Rover service manual, section 51, page 1 at the sectional drawing showing the rear wheel hub, (item 4) and the disc (item 10) and I can see no reason why a grease nipple cannot be tapped and fitted into the hub to permit easy greasing of the two hub bearings without having to remove the halfshafts and inner bearing in order to do so. Has anyone done this ? Quote Link to comment Share on other sites More sharing options...
Maverik Posted November 5, 2015 Share Posted November 5, 2015 Can't see any reason why you couldn't do it, but I'd be a bit sceptical as to the actual effectiveness of such action. I must go into my wheel bearings every couple of years usually for brake maintenance, I'll scrape the old grease out and pack new in and box it up. I've never seen the need to top it up... something else to think about is the venting of the old grease where's it going to pop out... your either going to push it into your axle case or its going to pop out behind the hub and make a god awful mess....

vulcan bomber Posted November 5, 2015 Share Posted November 5, 2015 And it'd take a tub of greasep to fill the void between the bearings. I only ever look at them when I change discs or they come loose. I always change the hub seals when ever the hub is off. Quote Link to comment Share on other sites More sharing options...
Boydie Posted November 5, 2015 Author Share Posted November 5, 2015 Points noted and I will ponder on my next course of action, incidentally I only use Lithium based high temp bearing Grease - very similar to that used on the front CV joints, as you know this turns to a liquid when "working" and goes back to a semi-solid when idle, I prefer to use it as even as a thick liquid it gives far better lubrication to the bearings than conventional bearing grease.

honitonhobbit Posted November 5, 2015 Share Posted November 5, 2015 I was looking under a Humber Sceptre Mk2 earlier today. Nice car - it's got a Holbay 1725 under the bonnet. There are 37 grease nipples for the 1000mile service. I counted them Quote Link to comment Share on other sites More sharing options...
qwakers Posted November 5, 2015 Share Posted November 5, 2015 christ id have to grease those every 4 days! Quote Link to comment Share on other sites More sharing options...
Nigelw Posted November 5, 2015 Share Posted November 5, 2015 Why not do as I did Iain and rip out the seal in the axle and let the diff oil circulate through the bearings, I did that on all four corners, much prefer oil lubed wheel bearings, at the most they just need nipped up once in a while, I changed the greased bearings as often as I'd adjust a set of oil lubed bearings. Key advantages being that oil, cleans, cools and lubricates, grease lubricates to a point, but once its migrated off, bearings rapidly wear out.

Boydie Posted November 8, 2015 Author Share Posted November 8, 2015 Sounds a plan Nigel, did you change the type of oil used or stayed with normal differential oil? Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted November 8, 2015 Share Posted November 8, 2015 The early RRC rear wheel bearings are wet and its just ep90 diff oil. Its very simple and works very well, thats how my back axle is and its been kicking around since the late seventies. Taking the oil seals out of a later axle effectively does the same thing and in my view is a sensible improvement, the only downside is that the hub seals and lands have to be in tip top condition ... but they should be anyway. LR themselves think its a good setup as the seal fails after a time and does the modification for you :-) HTH Quote Link to comment Share on other sites More sharing options...
Nigelw Posted November 8, 2015 Share Posted November 8, 2015 Straight 80/90W hypoid gear oil. Rear drive shaft flanges benefit from a gasket over RTV I've found, front drive members on mine got swapped out for Bearmach HD ones with screw on cap with a few turns ptfe to seal, but was told that a felt pad and a dollop of Vaseline inside the plastic cap is cheaper and retains the factory engineered "shear point" as in splines of DM should wring off before serious damage occurs Quote Link to comment Share on other sites More sharing options...
Boydie Posted November 8, 2015 Author Share Posted November 8, 2015 I'll do it today - weather permitting ! Quote Link to comment Share on other sites More sharing options...
