Diff modifications in ChCh

Post by Patroler »

Hi guys

Looking for a good mechanic who can change my c/wheel & pinions in or around Christchurch, I can't do it during the week so would preferably be a saturday job.

Anyone know of someone?

Cheers

I'd second that, otherwise go to a diff specilist.

Here's the diff specialist
As copied from a prevoius post of mine

Give Don Mathias at The Machine Shop a call.
Ph wk 374 6184 or cell 027 349 5089. Workshop just off Gasson St in Chch.

He specialises in motorsport engineering, from adjustable uprights and brake mods, to 500hp capable, close-ratio toyota boxes and puts these behind anything from Starions, Celicas thru to RWD Evo's engined beasties. Both endurance rally and race. He used to build successful Sprint Cars. He does the finer engineering details on Trevor Crowe's rear engined V8 Justy and Scoda.

Don has modified and rebuilt my rear diff, the odd vintage car gear box for me and I have worked along side him for a number of years, going back 10 years ago. He is one of the best Fitter & Turner tradesman I know and a very practical thinking Engineer. (I am one too, as well as being a Mech. Engineer)

In my Prado Diff we straightened the axles, replaced the outer bearings and made mods to the outer seals / sealing system, repaired the E-locker mechanism, put the earlier type Cw & P into the V6 housing (massively different shimming requirements from factory) and made up a solid spacer for the pinion.

He made all the various bearing pullers and pressing devices to remove and install toyota Hilux axle and diff bearings.

Lots of rally cars use Hilux/Prado rear axles so he sets these up regularly.

He knows how to set pre-loads and meshing correctly especially in high load applications which is more than I can say for some local mechanics.
