Recently I was going through archived travel images to illustrate an article for Wheels Afield magazine. While doing so, I noticed a consistent thread running through our photos of Africa and Australia: A significant number of them were of me working on the hubs of various vehicles. There were two sequences of me rigging bodge wire fixes to keep grease caps on the rear hubs of Land Rovers, and one of me (repeatedly) tightening the nuts on the full-floating axle of a 45-Series Land Cruiser. All these, incidentally, involved the use of a multi-tool because the vehicle in question hadn’t been equipped by its supplier with adequate tools.
Then there was our last trip through Australia, during which we found that a mechanic in Adelaide had comprehensively screwed up a simple front hub and bearing service on our Troopy, leaving one loose and one reassembled incorrectly so that it would not engage. (There was also a different color of grease in each hub, leading to guesses that he had actually only “serviced”—i.e. buggered—one.)
It brought home what torture the hubs of an expedition vehicle go through on the rough tracks of the world. The number one cause of backcountry breakdowns is still (according to several sources) tire punctures, the second is battery problems. I’d bet the third is hub and wheel-bearing issues, especially if you include the assembly all the way in to the CV or Birfield.
Therefore I’ve decided that from now on, I’ll make sure our spares kit includes a complete hub servicing kit including bearings and seals. It will take up less space than a hard-cover book but could save a lot of time and grief.
I’ll also make sure I have along the correct special tools needed. In Australia when I disassembled the hubs I was faced with the external snap ring Toyota uses on these hubs.
Graham and I had a decent selection of tools with us, but nothing suited to this fiendish part. Graham finally filed the outside ends of a pair of needle-nose pliers flat, which worked pretty well. How much easier it would have been if I’d had these Knipex pliers made for the job.
Deciding which and how many spare parts is always a conundrum, and will vary with the length, remoteness, and difficulty of the journey. But a complete hub kit is compact and cheap enough to be a permanent fixture along with fuses and belts.
