PATROL STEERING BOX & DRIVELINE DRAMAS ON MY BARRA LANDCRUISER - Barra T FJ 45/ 80 series Ep. #21 

Yes i am going though the whole build series likening and watching all the videos. 😂 really ending what you have created both the cruzer and the videos ❤

If you find a tb48 gu rear diff, you'll have a drum brake handbrake set up like an 80 series, will just need to change your mounts again

extra option use a duble carden joint driveshaft and rotate pinion up to point at transfer case output. but still 19 degrees is nothing if it doesn't bind. you can replace a uni in half hour and they're cheap. vibration is a non issue as long as the t case output and pinion are parallel for a uni uni application.

Don't stress Bro, go Double Cardin I have a SWB Manual JK Wrangler with 4" lift on 37"s ie big angles and short rear shaft . I upgraded to 1350 Spicer double Cardin uni at trans case 160km ago. 3.8 Petrol is custom built and running 12psi boost. Gets abused off-road, broke heaps of things but never the tail shaft. Oh also double locked and the Rubicon has a rediculous 70:1 final drive in 1st low so on high traction rocks drivetrain has to transfer massive torque loads. Good Luck CB Any tailshaft shop will make one up just give me flange to flange measurements at ride height.

Nice one Richard, a lot of head scratching mate haha. Seeya Rob

Love this project!

You could use dual uni joins in one end of the tail shaft as the Nissan patrol 260 series use. This is a European model so you can’t find it overseas. But it runs center diff on the rear axel and a normal patrol gearbox/ transfer as you se on the y60 but it’s build in to the k160 body

Worth mentioning only the H260 calipers on GU is different to GQ calipers. All other GU rear calipers (H233) are same as all GQ rear calipers.

You could use Toyota double u joints or cardon shaft joints

I mentioned during one of your videos (sorry I can't find it now) that you designed the welding table you use? Do still have the the design and would you sell the plans?

Loving the content keep it coming 🤙

I've got Subaru L series calipers on my LN106 Hilux. The handbrake isn't the best, I found it very hard to get enough clamping force but maybe that was due to the straigth pull handbrake under the steering column. On mine it does hold but on any decent incline I first have to press the brake pedal before pulling the hand brake or it will roll.

You could also change the rear diff to a h233 and use a front diff centre housing with the rear centre kinda making a off set housing less angle to

Have you thought about using a hydraulic handbrake like the ones used in drift and rally cars with a clicking/locking mechanisms on the handle to hold itself on when you let go?

The GQ rear brake cradle bolts up to the GU housing then just follow the procedure from that patrol4x4 thread. I have done the same on my conversion but I'm not sure I'm going to be happy with them let alone pass the engineering test. I still need to bed the new pads and rotors in but I'm not holding my breath. What ever you choose you will need a custom shaft so I'm not sure what's the problem. Yeah a double cardon joint is expensive but way less than the work you are proposing.

Awesome content as always. If you remake the cross member, I've got another $0.02 worth for you. I use 44mm DOM tubing, attached to the inside of the chassis rails, suitably bent to go down and under the case, but with shackle bush(Ford Escort, from memory) rubbers, either side of the case, instead of the factory rubber mount, below the case. For two reasons, the factory mount hangs stupidly low(the bolts even lower) and smooth chassis rail lower outer edges, stop rock hang ups and mangled bolt heads. Brembo, TRW and Willwood all now sell electric handbrake(ebrake) calipers, disclaimer, I've never used them, but the VE Commodore's use of an electric setup, should clear the way through engineering. Alternatively, Atlas cases are short, centre rear output and there's a handbrake option, oh and a front dig handbrake U turn, gets everyone's attention.

Do what flex79 done and put that disc brake thingo on the back of the 80 transfer

For a park brake, why not use something like a Jamar Park-Loc? It's a hydraulic device.

Nice work. Though I do wonder if you are starting to get too far away from just being able to pick up spares easily in your travels. It's getting pretty complicated as to what part is used where. I hope your writing all this down. Great vid again Richard.

Any thoughts on using a double cardon joint?

Don't worry it's a engineer thing

C4 is known for being very short. I don’t know whether you can get an overdrive for it though?

Boosted built garage on RU-vid I think have done Transfer case mounted hand brake kits for 80 series

Didn't want to use weldthrough on the inside of the bolt protection portion to save it rusting later.

Why don’t you use an electric hand brake ?

Any chance of selling or sharing the designs for that plate for the steering box conversion?

She’d built make a transfer case hand brake

FJGU?

why not just start with a patrol chassis

Ive missed a couple of episodes. Why the hell are you even considering a patrol rear diff ???? You are making a big headache for no real reason if its for strength think again buil the diff with a solid hemisphere eg locker put in some 10mm arp studs in the hubs and Fermin send it man. That thing is light compared to my 3.5 ton 5.8 isuzu truck motored 80.
