5.29 into hilux

Post by LUXon37s »

Hi all

I just picked up a 5.29 hiace diff for free and was wondering what needs doing to fit this to my hilux

Are the axle splines the same as my '97 hilux

Also if it will fit how much am i looking at to buy a second centre for the front

Any help would be greatfull

u may need 2 redo bearings but if not make suer the backlash is ok.

only other thing is the drive flange will have a different bolt pattern, 2 will line up and 2 wont, just bolt down the 2 that line up and drill out the others. or get the flange changed over at a diff shop.

i paid 125 inc freight from melbourne 2 newcastle 4 mine. thats a complete diff centre

Check the pinion Nut first before you fit it. If it has a 30mm nut its a Fine Spline Pinion and this is good but if it has a 28mm nut then its a course spline pinion and this is Bad.

Although i know a guy running 5.29 course splines front and rear in a zook with lockrights and has had no problems at all but it is light.

I've just finished putting mine in tonight.
The pinion flange bolt holes are nothing alike on mine, so I just redrilled the holes.
I don't think that the flanges are interchangable as they have different splines.
Other than that they bolt straight in.

What is the issue with the fine and course splines ?

Is there a difference in strength between hiace 5.29 and hilux 4.88 ?

The course spline ones came out of early hiace vans.

Its a strength issue. The pinion is prone to snapping. The axle spl;ines are still both the same and they both bolt in the same. You just cant swap the pinion flanges over. So there is no choice but drilling the flange on a course spline type.

Yes the 5.29 is weaker than a 4.88. The pinion is smaller on the 5.29.

coarse/fine has to do with a solid or crushable sleave.


I have 5.29 and have had them for over 2 years, i have broken one front about 20 cv's and never a rear. I think setup right you should be sweet.

they are available in HP and IFS ctr for the front but are ex USA.
