Long story short, initially 80 series bearings sent to me for my 82 fj 40 by Marlin but they did outstanding job sending me the correct ones when I figured it out. Nothing but kudos for Marlin, great product and service.

I attempted to use replacement bearings but felt like it required too much force to get them started. I enlisted help from local cruiser guy who brought his son in law, an exellent mechanic. After several tries and rubbing his head he felt like he wa sable to get the trunion started on lower portion of knuckle housing.

Today I attempted to finish job, thought preload too light so decided to check shims again. When removing the lower trunion its pretty well stuck! the bearing was destroyed when trying to remove it from the trunion.

I have included the pics of new and old bearings and races. I just can't figure out what the problem is but nothing going back together like it should!

Are the bearings and races incorrect again? they are obviously different.

New ones are koyo, say 30303r hi-cap, where original say tr0305a

I have to figure out how to get the remaining portion of bearing off trunion!
Any help would be appreciated
Thanks

bump after finally getting the pics loaded.
Thanks Woody for the help
 
I don't tlike the looks of the new ones, not enough taper in the bearing. I would look for some with the same taper as the ones you took out.

Were the new ones from Marlin? I've bought a number of knuckle kits from him and they always looked like the old ones you took out (right), not the new ones (left).
 
Yep, second set from Marlin's also after it was determined my first set were for an 80 series. Guess I will call again tomorrow.

Sheesh this has been a royal pain in butt. Was hoping to finish this weekend so I could drive her a bit with top off.

Probably going to take trunion to machine shop to help remove the remnants of bearing.
 
Man that sucks. I'm surpised that Marlin would send you the wrong ones twice. If you go with another vendor I have gotten a set from Kurt from Cruiser Outfitters. Great guy to deal with.
 
I'm thinking maybe when you said you had an "82 landcruiser" whoever took your order thought that meant an 80-series.

Doh.

I have this problem a lot when I talk about my "73"... which is a 1985 BJ73.
 
Don't use those bearings - the bearings you want are KOYO TRO305AF4 (will have that part number on the box and part number on the bearing is TR305A).
You can order them from cruiseroutfitters for about $17 each or other vendors.
 
Yep, figured that one out the hard way. Called marlin and they a looking into it again, 3rd times the charm right??

"What we got here is a failure to communicate"

I always say things could be worse, it is just a car in the big picture.
 
I just rebuilt my knuckles a month or so ago and got my trunion bearings from the toyota dealership. I am running FJ60 axles though, but I think the bearings are the same from the 40 and the 60.
 
Talked with Marlin Crawler, the bearings on right are what they prefer in the 40. They feel like allows for better movement.

Unfortunately my experience hasn't been positive with their bearings. I ordered a new set of bearings from cruiser outfitters today. Think I will try those and go from there.

How did they work out?

Thanks again for the order!

Ran across this old thread but wanted to add something in case anyone else is confused on knuckle bearings, because it pops up when you start punching in bearing numbers.
The bearings on the left are 30303R not 30303D. -81 60 series Toyota specs 30303D which has a taper much closer to the TR0305A(F4) on the right.
From what I can tell 30303R (shown above left) was never specified.
The TR0305AF4 is still the more up-to-date option based on the diagrams though.

Furthermore, seems like toyota superseded 90366-17001 (koyo TR0305A) with 90366-17007 which seems to be a Koyo TR0305C-9, but this interestingly does not pull up anything on the Koyo website. Only TR0305AF4 comes up.

Please take this all with a grain of salt, this is just my personal research, I'm not a parts expert.
