Well, while I wait for the new rear driveshaft, I decided to shim my rear diff with the ebay shim kit. All went well except for:

#1: One of the four spherical shims behind the spider gears was deeply scored. Anyone know if getting another one is even possible? Keep in mind that these shims keep the spider gears lined up with the drive gear. Any wear means a widening gap, leading to gear wear. I've upped the oil to a heavier grade, and will be drilling a larger oil hole in place of the 1/4" one there now.

I figure cutting a new shim out of shimstock and using the spider gear to shape it would probably work, but I'd still prefer to buy a new one. Likely that is near impossible.

#2 is minor: The 12 replacement nuts that lock the ring gear on interfere with the teeth. Buy 12 lockwashers before doing this mod. You also need a vernier or 1" mike, plus feeler guages, plus a bearing puller (with at least 3.5" clearance) to complete this job.

That's about it. Now for the front diff...

You should be able to reflaten the existing washer if it's not completely destroyed. Rocmoc and I did that to one of his and it worked fine. Your right about using the spider gear and the inside of the cage to reform the washer or form a new one.. That is what we did. You won't find a replacement. If you make a new one, shimstock is usually hardened and won't shape nor provide the correct bearing surface. If it's soft your ok. It should be a soft steel, even cold rolled sheet should work fine, bearing brass would be great.

The 12 nuts shouldn't interfer with the ring gear teeth even though they are very close. The pinion gear shouldn't hit them either. I'm not going to say that it is impossible but we haven't yet had any problems. The lock washers should be fine but just make sure that everything clears when the gear is turning. Also be sure to still use the loc-tite because the lock washers won't be able to dig in to the hardened surface very well. Make sure things are super clean for the loc-tite to hold properly and get the bolts good and tight. When I do them, I get them as tight as I can, any more would strip the hex head out. Also use a good quality hex wrench or it will just round the end.

Thanks Lenny.

All nuts definitely contact the gear teeth, to the point I couldn't properly tighten some against the face. I did LT everything, including the nuts.

Once I go back home end of the year, I'll pass by my old job and make a few extra shims just in case. If I have a chance and am confident I can measure the rad properly, I'll make a mold and press new ones at work, leaving me with a few extra sets for any who might need them.

I don't recommend not using the nuts Use the nuts, don't cut corners. Get every bit of extra security you can. With the nuts, you cut the chance of the bolts ever loosening by 50%.

I had to replace one of the spider shims also and was lucky enough to find a perfect replacement at a local drive line shop, He thought they came out of a toyota rear end.

I didn't bother with the lock nuts, just used lock tite.

I figure you know this question is coming, but I'll ask it anyway in the hopes you might know but forgot to mention it:

What model Toyota was it? This is a pretty important part...

If you're not successful finding them, you can likely get a machine shop to make you some for cheap. They're real simple.

Rocmoc, you don't have any spherical spider gear washers laying around, do you? The one damaged one I have is usable, but considering my machine has only 1000 miles, I wouldn't mind having some spares.

Tinman, sorry looked once before and I don't have any spare spider gear washers. Most everything else. Will be looking today.

The washer that Lenny fixed was in one of my nearly new, unsed spare diffs. They messed it up at the factory in one of the upgraded diffs with the clips on the bolts. The washer may not have been fixable if it had be used on the ground for a while.

I guess I'll go ahead and order stuff for making another batch of diff upgrade kit. Probably take another month yet before I'll have any to ship out. I'll send everyone a PM when there ready. Tinman, I do know that the nuts do contact the very edge of the ring gear teeth and I do knpw that it is a bit of a pain to get them tight. I always use a smallish but top quality 1/2" open end wrench to do the job. The 1/2" wrench fits real tight on the nut and gives you a better chance of getting it real tight. Anyway, I'm going to try and find narrower nuts this time. I'll have to look harder because I couldn't find them before. It would be nicer to be able to put a socket over them to tighten.Being an 8mm x 1mm makes the thread size not real common and that is where the problem is. the more common is the 8mm x 1.25mm. Thanksfor your input.

Ahhh, so the kits come from you!

Great stuff, and nice instructions. I did use the 1/2 inch wrench for the reason you mentioned. The lockwashers worked fine though and with no clearance issues.

Now if we could only find out what Toyota Kinarfi got those spherical bearing washers from...

      New AXIS 550
      By Greg Kilgore
      Was at Lowe's over the weekend. The wife and I seen they have a new Axis 550. That thing is sharp. Has a complete door. Speakers in door. Bigger engine. Bench seats. New styling all the way around. Looks to be more air tight than my 2022 model. I really like the looks but $10k is out of my price range for now. Unless I could sell mine. And the resale on the Axis 500 is nothing.
      Went to the local wally world today. See a 4 person Polaris General 1000 on the back of a trailer. That Polaris looked exactly like a stretched version of the Axis 550. Even down to the vents in the windshield.
      Just wondering if anyone can confirm or deny the Axis 550 is a copy of the Polaris?

      Hisun Sector 450 (2021) - help diagnose rear diff issue (short video included)
      By camojay
      When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
      Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
      Other info that may be useful:
      1400 miles on it
      Recently tightened the E brake
      P.s. never posted on this forum before, let me know if the video does not work

      Good mornin' all. Just joined.
      By diamondjfarm
      I got an old 2003 Arctic Cat 375 Auto, and just bought a 2008 AC 650 side by side. Got a new starter, solenoid, and battery for the 650. Gonna change the crankcase oil and filter while I'm at it.
      Anything I oughta watch out for from them that's done the starter/solenoid on this model?
      Don't have a manual yet for the 650. Any recommendations for oil weight/grade?
      Thanks.

      Anyone have a Bad Boy Bandit?
      By mac66
      Apparently, these are Hisun or at least they use Hisun engines. I can't find much info on them online yet.  Ran across a used one with just 100 miles on it as a very reasonable price.  Just curious.
      Okay, more info...they are owned by Textron Corp who also owns Bell Helicopter, Cessna & Beechcraft aircraft, Ez-Go & Cushman and Arctic Cat and a bunch of other companies.
      So are thy cheap Chinese crap machines or are they good to go?

      Hisun will not change gears while running
      By Buck
      My father-in-law has a Hisun 750.  It has started to not change gears while running.  He can turn it off, change gears, then restart and it will change.  I thought it might have something to do with the brake but can’t find any info.  Thanks in advance for any info.
