Bearings, the first one was a cheap unknown rebuild which failed very quickly the following two have been Ashcroft rebuilds, but it is still the bearings that fail. Oil is changed every 24k, and always has been in my ownership. It has 340k on the clock, and I am currently doing 23-30k a year. A lot of that is company mileage however so even if the gearbox does go every couple of years, the mileage allowance more than covers the parts, it is just annoying I have to change it that often.

Not surprised you find it annoying! So, you're on to your second Ashcroft rebuilt box. What did they say when their first one went at 80K?
Presumably, if you're doing up to 30K miles per year there must be quite a few long, non stop journeys in there. I wonder if the gear box is running a bit hot?

Think you can get an oil cooler set up for the lt77, remember seeing one on an old disco v8.

I think I'd be investigating one, even if just to check out cost and hassle to install at first.

As good as their customer service and reputation is. They were not interested because they only guarantee them for 12 months.
I am already running a larger sump on the transfer box. So maybe worth investigating a cooler for the gearbox.

Your comments make me really pleased I didn’t go for a recon box now. On the flip side, I hope I get more than 60K out of my new bearings. Interestingly, the bearings supplied don’t quite match the old Timken part numbers exactly. I wonder if a “lesser” spec bearing has been supplied to save costs?

How do you get that long out of a gearbox? Recently I cannot get a gearbox (recon) to last so the clutch gets replaced when the next gearbox refurb happens rather than when the clutch wears. I got 200k out of the original but the last two has been 60k and 80k, and I am now on my 4th.

I occasionally tow a bike, yeah, I own a Husky....My wagon leads a very easy life. Did the disco transfer box ratio change wnen I did the clutch and this quitened things down somewhat. Whilst I had the transfer box apart I was surprised at the build up of smegma within, given I changed the oils at reccomended intervals.
