Folks, I know this forum is all about things gator. But maybe someone has experience with a Buck? It's one tough son-of-a-gun and has served me well for MANY years. I've never done anything but change engine oil/filters/batteries. It just goes and goes. But I'm getting concerned about the front differential. It has started to "yowl" in reverse. I have no idea of the lube required - I'm sure its way past time to change it out.

Advice? Lube type?

Thx, JRH

I have the original Ops manual. In the maintenance section for service intervals anything other than the most simple of simple tasks state "Dealer Service Required" or something to the same. As for Lubrication nothing is specified for the differentials.

Over all the years it still has just less than 100 hours on it. The seals are tight without any signs of seepage. Overall its had just transportation duty. It has the power and gearing of much more but its over all weight is less than adequate for safety. It's just a low speed, light load work-a-holic with a solid rear axle, swing-arm suspension. I've always loved the geared automatic/manual xmission.

Guess I'll have to find and buy the danged shop manual.

Mr 200mph, Thank you sincerely. It's not in my OEM manual but no matter - I will absolve my lack of maintenance sins tomorrow. I just happened to have a case of gear lube for everything else ready for this small project. If the lube comes out nasty I'll submit myself for a threshing.

The Buck gets more use now. The Land Cruiser in the background has yet another sheared front axle. Sigh. Use a tractor when a tractor is justified. A Land Cruiser is not a tractor. It wouldn't be problem except for a gov-locker in the front. The axles just can't handle a locker in low range.

Good luck with everything!!!

Here is a link to the Operators Manual for the Buck 500.

Look at the index on left hand side under 鈥淪pecifications鈥 from there you should have all the information you requested.
