  Hello. I am new here,I have a JM354. Was using it on Monday and going down hill had the front left wheel lock up. Checked for rocks.All clear.So it looks like it is one of the gears in the axle housing? Will pull down today. It looks like the place to start is the upper axle cover/steering arms? Thanks for the input!

  I would pull the Left drive assembly off first, then you can turn the part the wheel bolts(Driving shaft) to determine if it's in the left front drive or in the 4 x 4 box.Do you have the parts manuals for your tractor ?
  
  Let us know if we can help, we keep all the parts in stock

  Thanks Tom.
  
  After loading on the trailer it seamed to be ok,but will pulldown and have a look see.Other wheel was working,so it must be a tooth flooting in the housing?

  yep,top gear bearing.May have been rust but I have not been in water? Maybe just bad? Can the bearings be had from Japan?China maybe the problem?
  
  Going to pull down the other side just to check.
  
  Thanks Randall

  I had a nearly identical problem with my 354LE. I was certain it was a defect, but now I'm not so sure. I think a slightly low oil level in the axle housing will starve that bearing of lubrication because of its height above the housing. Anyway, I regularly check that oil level now, and keep it well filled – so far, so good. I also make sure the venting tube on the filler cap is clear.
  
  Good Luck, Mike

  Thanks Mike.
  
  That maybe it? I am going to hand grease the top bearing and keep a eye on the gear lub! I have been working some very uneven ground.
  
  What lub did you refill the axle with?

  If you're working the tractor hard during the summer there in Glendale, I'd suggest the heavier 90W140 gear oil, though the 80W90 will probably do okay, too. I've been using the 80W90 in my 304 Jinma transmission and front drive here in the tropics with no problems at all.

  Thanks Rich! That was what I was thinking.
  
  Built a drain plug with a magnet on it, Had to weld a nut on the plug to get it out. What a pain!

  Photo of new plug. The hole is 1/8 ” NPT. So I just used a socket head and J/B weleded it to the end. Also in the photo is the old plug with the rouned over head with the nut welded on to remove it.
  
  Hope this will help others? Randall
