Seems nobody lists this setup, so I'm not able to get new shoes. I'm gonna use parts off the yellow one to convert to ebrake to use the rear drums. The backing plates are from that setup, so I should just need to find cables, since the yellow ones are no good. Also found a bad u-joint on the rear driveshaft. I believe it is an older sj410 setup if you are having trouble finding parts listings Link to comment Share on other sites More sharing options...

Now what is the best course of action, I have no idea. There's lots of Zuk specialists on the web! And ideas. Aftermarket driveshaft beak, disc brake conversions, etc. Link to comment Share on other sites More sharing options...

SQRLPWR Posted September 1, 2016 Author Report Share Posted September 1, 2016 Mine's an 85 - early Sami, which only ran till 88.5....so parts unique to it seem to be hard to find locally. No matter, I've ordered the front-to-left and right ebrake cables, so I'll just convert to ebrake on the rear drums since the drums I got off Chad came from a rig with that setup and have all the parts required. Drained the rear end....well tried, she aint flowing too good LOL Made an exhaust pipe extension because the pipe exits at my seat, and it's no fun getting gassed LOL Replaced a bad rear driveshaft ujoint Bought a big old drum of 80/90 GL-5 for the diffs, tcase & trans....all uses the same oil apparently.

flibby Posted September 1, 2016 Report Share Posted September 1, 2016 lol, nice and clean looks like caramel coming out of the rear end Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 1, 2016 Author Report Share Posted September 1, 2016 LOL...sure dont smell like caramel Tcase oil seal is in. Interestingly, the old seal was sitting a hair above the surface. When I installed the new seal, it sat 1/4 inch inside the hole. IDK if that means anything...maybe too much tcase pressure blowing the seal out ? Rear diff has fresh oil and I took it out for a drive without the rear driveshaft in FWD. The whine is still there. So, I'm gonna throw in the yellow tcase. Dave seems to think early vs late Sami tcases are different. My guess is just the rear output flange vs. Ebrake setup. I'll see when I pull it out ...of course it could be the transmission whining too. Link to comment Share on other sites More sharing options...
sar4x4 Posted September 1, 2016 Report Share Posted September 1, 2016 Where is the whine? Because of course if its in the rear end the ring and pinion could still whine as its turned by the axle shafts. However, I'd guess with the strain on the r and p coming from the ring side from the axle shafts and not the pinion side from the driveshaft the whine would be a very different pitch if at all. Dunno! Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 1, 2016 Author Report Share Posted September 1, 2016 I think I know it's not the rear, because the pitch is directly proportional to load...and it makes the noise in FWD as I took the rear driveshaft out. It's loud when u get to 70km/h This is the exact noise Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 1, 2016 Author Report Share Posted September 1, 2016 tcase 2 is in...but they made the flanges a little bit bigger on the later Sami tcase. so I'll need to swap out the driveshaft yolks off the yellow one..... Link to comment Share on other sites More sharing options...
sar4x4 Posted September 1, 2016 Report Share Posted September 1, 2016 There is never such as thing as a 'Direct Swap', lol. Oh wait, maybe swapping the Chev Dana 60 in for my Chev 10-bolt front? Well, at the very least it had a different wheel bolt pattern, necessitating a change in wheels! Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 1, 2016 Author Report Share Posted September 1, 2016 I thought I'd got lucky after taking a bunch of measurements for flange to flange widths. I totally forgot bolt pattern LOL. Oh well Link to comment Share on other sites More sharing options...
Lil'monster Posted September 1, 2016 Report Share Posted September 1, 2016 Just redrill the flanges . I do it with toy ones all the time Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 1, 2016 Author Report Share Posted September 1, 2016 Good idea!! I pulled the shafts outta the yellow one and will swap the tcase ends since they're on a slip yoke This has some aluminum spacers too. Presumably for the little extra height the YJ leafs give.

SQRLPWR Posted September 2, 2016 Author Report Share Posted September 2, 2016 I'd heard nothing since ordering the parking brake cables from The Wrench Monkey. So I called them. Seems they were sat on my order (again) because they didn't have stock, even tho their web page said in stock. A call or email would have been nice. That's strike 2. Order cancelled and Rockauto order placed. Link to comment Share on other sites More sharing options...

I only see flanged tc yokes in the pictures, meaning there is a slip joint in the driveshaft (or propeller shaft as the Japanese manuals call them). Those flanges are usually mounted on a splined (output) shaft, presumably with a staked nut holding them on? Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 2, 2016 Author Report Share Posted September 2, 2016 sorry, yes, my bad....the slip part is in the shaft for the front and rear driveshafts, not the yoke. I got my terminology messed up LOL. The transmission driveshaft has a slip yoke, so that just got swapped out. Link to comment Share on other sites More sharing options...
SQRLPWR Posted September 2, 2016 Author Report Share Posted September 2, 2016 Also, I just found out the early 410 tcases have a 12% reduction from the later 413 tcases So there are 3 Sami/SJ tcases; Early 410 - no 4x4 switch, small shafts. Small yoke bolt pattern. Flanges not interchangeable to late 410 or 413. 12% gear reduction from 413. Late 410 - 4x4 switch, larger shafts. Small yoke bolt pattern. Flanges will swap to 413. 413 - 4x4 switch, larger shafts. Larger yoke bolt pattern. Flanges will swap to late 410. My '85 SJ has the late 410 tcase.....but who's to say it's original to the Sami ? ...probably not. If my noise is still apparent after my 413 swap, then I'll be going back to the 410 Link to comment Share on other sites More sharing options...
sar4x4 Posted September 2, 2016 Report Share Posted September 2, 2016 Divorced T-case? Despite my being picky on the slip yoke business, I hadn't even noticed the implication of three flanges in the picture! The 'jack shaft' between the transmission and the transfer case must be mighty short, as well as the rear driveshaft? Keep it 'stock' height or you will have driveshaft and pinion angle problems?

SQRLPWR Posted September 3, 2016 Author Report Share Posted September 3, 2016 I ordered a strapped bikini top, 2 weeks before the Summer Event hoping it would arrive in time. Well, I've been trying to get hold of the guy I bought it off, but no luck. I had a pleasant surprise for me in the mailbox yesterday ! Best of all, he sent it USPS....no duty I'm missing the original soft top hoop, and that's where the rear straps are meant to attach. The hoops seem to be rare, so I'll probably get something boat-ish to hook the strap around. Link to comment Share on other sites More sharing options...

sar4x4 Posted September 3, 2016 Report Share Posted September 3, 2016 Do you have a hard top or full soft top for the winter? I forget if you've mentioned it before. And now I've got the idea in my head that I'm putting my hard top on for the cooler months.... Maybe run the bikini top next summer.... such choices!
