Change front differential fluid 1987 Suzuki LT4WD

Recommended Posts

Can anyone point me to a good set of instructions for changing front diff oil on a 1987 Suzuki LT4WD? I can almost guess which bolts are drain & fill... but I've been wrong before... 😆 

I found some partial posts on other forums and they linked out to dead images and whatnot. Any help appreciated. 

This thing is running pretty good, got the front brakes back to life, electric start works fine, seat cover fixed up, plastics stitched back together...

Nice work ! Love bringing an old bike back to life.   Changing the diff fluid is not that difficult. The only thing you have to do ahead of time is oil the fill plug and drain plug with penetration spray oil a day ahead of time. It will strip otherwise. If there is no drain plug buy a small hand pump to remove the old oil. Pump it out and put in new ! Bam done.

yep on my bayou, there were two big hex head looking plugs.  one was about half way up on the differential and the other was on the bottom.  You want to fill diff fluid up to the fill plug till it starts dribbling out

Drain bolt on the bottom, fill hole on the side. Fill it to the bottom of the fill hole. You can do it with piece of clear tubing on a funnel, but 80/90w runs SLOWLY, so you'll have a lot in the tube by the time it's actually full. Over-filling isn't a huge issue, but it may leak out of the axle holes past the seals. Just make sure the vent isn't clogged. :)

you do not need a pump. ltf300 from these years has an oil drain on the underside and an inlet on the side

Some of these fill plug holes are hard to get to and fill, so I like filling through the vent tube with the fill plug out and watch for a trickle of fluid out the fill plug when full.
