More of the same, The more it runs the better it sounds.
Shadetree may be right again, the binding is coming from the rear diff, the t-case and front diff, I changed fluid and they feel fine, So what are my options? replace bearings in the rear diff? replace ring and pinion? or swap the entire unit? Can I do it? basic hand tools?


I Cleaned the brakes (waiting on brake lever now) Spent two hours cleaning the tank, installed a fuel filter to be safe. I found some aluminum factory rhino wheels 7.5x12 and 6x12 4x110 pattern those and some matching tires should bring this pig into the 21st century looks wise. I will upload a pic of the plastics, they are a mess. I really don't know what to do about them.

The whirling noise has stopped, after the first couple starts it went away, may be it needed to be ran, sitting 5 years may have gotten a little stiff. While on jack stands and running, I shifted through all the gears and even into reverse, all gears works fine no issues (at least with no load on them).

Lets see what tomorrow brings. I want to see it on the ground and moving under its own power!

changing the ring gear and pinion gear in the rear diff is not too hard ?, the worst part is replacing the pinion needle bearing !. it wont' be easy to get the old pinion needle bearing out, but it can be done !.

So today has been fun, I scored some aluminum wheels and some new take off 25in tall tires.
Found a guy on eBay, who rebuilds the rear diffs for $185 and that includes a warranty and free return shipping.
Also talked to the guy in Arkansas who has new plastics, we are working on what shipping through fastenal might be for a full set.
fingers crossed on that. locally I get get some used plastics from a junk yard but there then there 26 years old.

I ran through all the gears and reverse all the dash lights work as they should and the headlight switch is working along with high and low, the bulbs are toast.

So now it comes down to plastics, rear diff, and a leaky front driveshaft seal (t-case side), it didn't start leaking until after I changed the fluid. lol.

Below you will see the new wheels, I may keep these they weight almost nothing, the terrible state of the plastics and the new knobby tires 25in on the left side of my v treads.
Enjoy the photos

Parts

I can not find the seal part number anywhere for the front output drive shaft of the transfercase.

Also would any other fender set or model would fit my 93 trx300. something newer? something cheaper?

Thanks WIlson

Partzilla didn't list it. Thank you.
I feel like there should be a 6ft privacy fence between us. Lol
Thanks again

it was listed under the drive shaft on partzilla, just like everything else, they are removing parts for the trx300's slowly one part at a time, wont be long, and all parts for them will not be around.

Jeep what’s the frame diff—advantages for builds mebbe? I have a 93 with i think a single frame pipe running under the tank. It has a fan, too.
Well the first gens are harder to find parts for, and you can't use a Wide Open 424 on them without modifying it to fit because nobody makes a 424 for the first gens anymore.

I'm not sure if there's a benefit for the actual first gen frames in the mud, but some people seem to prefer the 1st gen bikes for mud bikes. The 88's had a BR cam in them from the factory, but I don't think any of the other 1st gens did, but I do think the 1st gen CDI's allowed for more RPM's.
@mac102004 could probably either verify what I've said, or tell me I'm wrong on every point.
