is there any problems with putting discs on the rear s/f diff of a fj40
some one told me that that had to much play
is this true?

he mite of had a CV problem coz on my 75series and its 16yrs old ive busted the same one twice and its affected my front diff i got arb air lockers
just b aware of the age i spose but i reakon it'd fine just ask the guys who fit it

flynn

rear not front

when you say to much play what are you refering too?


NICK

Are you talking a Semi Floating rear axle?

If so it could be done as long as you use a floating caliper like on the rear of a pajero.

I run Pajero rear discs and calipers on my hilux Semi Floating rear axle with no problems.

when he says play, i am thinking that he cant get the pads to bite evenly????


i know guts did have this problem and the back was locking up.


NICK

have hilux discs and caplers

and yes semi floating
was told seems there held in by a c clip thay would move in and out

you can use the hilux disks but not the calipers, you have to use a floating caliper.

I have subaru calipers on the rear of my bundera which is semi floating, it works well.

I would like to have rear discs on the back of my 40. Does anyone know what model, year suburu calipers with parking handbrake can be used.
Where can i get the caliper bracket made in Sydney.

early - mid 80's from memory. I just go to pick'n'payless and choose off whatever they've got there.

What is a semi floating rear axle. What is the easiest and best way to put Discs on the back of a 93 2.4 pety duel cab hilux. I noticed pajero discs is the way but is there a lot of mucking around. Cheers. Cris

a semi floaring rear axle is one with the axle and drive flange all one piece, eg hilux, patrol. the alternative is full floating, like a bus, or most landcruisers. you can tell the difference by whether or not there is a snout sticking out in the middle of the wheel. In a full floater, the axle shaft only transmits torque to the wheel, in a full floater, the axle also carries the vehicle weight.

GQ/GU rear disks fit without modification. the subaru calipers are cheap and plentiful, but require some minor mods (clearancing the bracket) to get them to go over the patrtol disks. mounting brackets are easy enough to make from flat plate 8 - 12 mm.

Cheers mate. Where me photos. lol

Have we got that ink yet??

ok guys u have me hooked . how do i do it and is it easy as ive had enuff of hving to take wheels and drums off to clean mud and crap out of my rears on my 84 dual cab . pics advice and what donor models . this is gunna happen.

thanks jamie

Throw away the S/F rear diff as they arnt to good, the rear axle bearing rollers run on the axle, so as the axle wore the bearing get loose and stay loose. Tried years ago the reclaim the axle by machining and fitting a bearing sleeve but it weakened the axle too much. Very hard to get good axle's now-a-days as it was a problem 15 years ago. The axle floating is a problem on S/F cruiser rear axle and cant be stopped. The F/F cruiser are easy to get hold off and relitivly cheap. You can still use your rear diff centre so you only need the axle housing, hubs and axles to convert.

thanks wally , so i just use say a 80 series housing . or can i use a pajero rear diff

incorrect. the bearing is a sealed unit bearing (single row ball bearing) which is a press fit on the axle shaft, and retained by an interference fit collar. inner oil seal runs on the retaining collar.

since we are discussing (primarily) Hilux type rear axles, there is nothing wrong with the semi floating setup - the axles are far form the weakest link in the chain and diff gears are far more likely to break first. And unless you want to go a whole lot wider, there aren't a lot of swap-in options into a Hilux.

in asnwer to the actual question, it's not hard but it can be time consuming. pick up some disks (80 series or GQ rears are cheap and easy to come by especially second handies) and some calipers that incorporate a handbrake setup (falcon, some toyota and nissan rears might work, but I think the easiest would be Subaru front calipers from about 1986 on (before that they had solid rotors so the calipers are too narrow). Then it's a matter of fitting it up and prototyping brackets to make sure everything fits and work. Use MDF (craftwood) to mock up your brackets, then when it all works, use the MDF as a template to make steel brackets. the plumbing and handbrake cables aren't rocket science.

YOU NEED TO GET YOUR FACTS RIGHT DUMBDUNCE AS THE SEMIFLOATING DIFFS WE ARE DISCUSSING WHERE THE 40 SERIES SEMI FLOATER PRE 1976 THAT USE A PARALLEL ROLLER BEARING THAT RUNS ON THE AXLE AND A "C" CLIP RETAINS THE AXLE. I NEVER QUOTED THE HILUX REAR AXLE IN THE DISCUSSION SO IT YOU THAT NEEDS TO GET YOUR FACTS RIGHT !

woah there, big fella!

the question to which you responded was about a Hilux axle. I never said you were right or wrong about the landcruiser semi floater. I agree the original discussion in this thread was about the Cruiser semi floater which is arguably not such a great axle, but the post to which you responded was about a hilux and you gave the guy a bum steer when you told him to throw away his perfectly serviceable hilux axle. Settle down, read the whole thread, and put your post in context.

peace, man!

INSERT SHAMELESS PLUG HERE

I got a set of front suby calipers for sale with the handbrake thing for sale

http://www.outerlimits4x4.com/PHP_Modul ... hp?t=64694

On reading my post im refering to cruiser axles, point taken as it first words appears to respond to the previous post on Hilux rear ends I could have "quoted" the original post and that would have clarified it. In the end is all in how you read it , ill always back up my words !

Wally.

Here`s my Hilux rear, sporting patrol disc`s and subaroo calipers with handbrake incoporated

Bentzook did ABT make up thoses mounting brackets for u??

Matt at M&M hand crafted them to suit. Their the only ones he has made. I think they are pretty good. There`s nothing he can`t make. Im
with his work.

With doing this mod I might get my 45 cruiser to stop, any tips on what the most popular calliper to use is, without the h/brake set up?
As ive still got H/brake set up on back of transfer.

If you still want to use the handbrake on the driveshaft, I`d suggest changing that for a Allpro disc handbrake aswell.
