I fitted up my Detroit locker on Monday to the Hilux.
Anyone go 2 Toyota for new carrier bearings just
lookout, they want $230 for em!! Ended up taking a grinder to a gear puller too remove the old ones. Then just Oil bathing em on the BBQ and slipping them onto the Detroit carrier.
The only thing is when I take off in 1st I get a kinda shudder/clunk as I come off the clutch feels like the locker engaging, If I ease of the Clutch slowly it’s hardly makes sound, is this normal with the Detroit Locker?

Backlash or slack between the driving and driven clutch teeth is an inherent part of the NoSPIN and necessary to permit
automatic operation when driving in forward and reverse. The total backlash in the driveline is increased by the amount of the
reduction between the ring gear and pinion. If the ring gear-pinion ratio is 5 to 1, the total backlash in the driveline with the
NoSPIN would be about 30°. This in turn is increased by clearances between planetary gear, sliding splines and the ring and
pinion gear. the total driveline slack can amount to as much as 1/4th turn of the driveline without being abnormal,
but if it exceeds 1/4 turn, other parts in the drivetrain could be checked.

Well Iv got no where near That much (¼) of a turn of slack in my drive line, I didn’t have a Dial indicator Mag Block so I just winged the gear Backlash for the ring and pinion, thought I might have F’ed it up, evidently the noise is normal on take off.
Cheers

I have had one for about 5 years now and notice no difference when driving forwards backwards or even sometimes sideways.
My Detroit was fitted by a specialist.
All the best

Here's a cut and paste from the PDF file i have , he hasn't emailed for it yet. Like me you had it installed by professionals.
....................................................................
Most NoSPIN/Detroit Locker differentials are designed to fit directly into the standard differential support case in the vehicle. Where it is not possible to fit the standard support case manufactured by the vehicle/axle maker, the NoSPIN differential is supplied with a case manufactured by Tractech. Therefore, two sets of installation instructions are provided.
NoSPIN differentials are easily installed in the field. However, it is recommended that a competent driveline mechanic do the work in that
tools of the trade are required.
The NoSPIN differential is designed to fit the components in the axle. No machining is required. The procedure is the same as it is for installing the original differential. A competent mechanic can install the NoSPIN in the same time required to replace the original differential.
Caution: It is recommended every safety precaution be practiced while performing the work when disassembling and reassembling axle components and when making all final adjustments.

The noise is normal at take off if you are on a slight curve or have turned while slowing down. OR if your tyre diameters are not exactly the same. Rotated tyres recently?
As soon as there is a speed difference between the two
wheels on the axle, the slower? wheel side will disengage ie the dogs will move out of mesh.
As you take off the dogs can be sitting on top of each other and then move back into mesh, hence the clunk.
Mine used to always clunk at a particular
intersection, where there was a slight turn to the left before the lights.
Try turning 90 degrees in a shopping centre on neutral throttle if you want to hear clunks.

Anyone know how much a detroit locker for the rear of a 75 series costs and where you could get one in
Perth?

Yeah, Id say the ring to pinion backlash is out a little.
Oh
well ill live with it, till i can be bothered adjusting it again.

For the sake of a seal, a bit of oil and some time I would pull it out and adjust it.
That's better than chipping or spalling a tooth and all that follows!!
You will be able to see the different wear pattern on the teeth caused by this change [use a bit of Moly paste if you can't] and can adjust the pinion up to get the result needed.

The gear pattern is Acceptable, I Checked that before I put it in, Backlash should be between .14-.18mm ideally, but as I didn’t have a dial indicator handy I kinda winged it, the drive line slack at the Pinion flange is a tad over 1/8 of a turn so
well inside the ¼ that is considered acceptable
Currently it raining so pulling it down agene isn’t a option and I fly back north for work Friday so the ute will be sitting anyway.
