Just had this fitted to my 8.75 rear;

It clanks going round corners and as i straighten it gives off quite a bang. No probs going in a straight line. I'm new to LSDs (no jokes) so not sure what to expect.

Its pretty basic and having looked more closely at the Richmond gear website i might have selcted the race/strip version.

Wonder if you engineer types could check the link nd give me an opinion

Description from the manufacturers site.

while i'm at it, anyone know the correct torque setting for the nuts that retain the half shafts? having probs finding it.

Miles, it depends how tight it is set up...some like em tight and they make a noise....infact the G.N is quiet as a mouse in a straight line but slow round corners you can hear the clutches grabbing, nowt wrong with it.

it normally a racers preference to have them set tight

Reading the description, I can understand why it makes all these noises. It certainly seems to be quite 'agricultural' in its design, but I would imagine it must be very strong as a result.

Looking at the picture I'm surprised the "dogs" don't get damaged engaging and dis-engaging, but maybe I'm missing something.

The Dana "Tru-traks" work using hypoid gears, so I'm told. That was silent and when turning you would have thought it was an open axle. All a mystery to me

Thanks for that, chaps. It really is agricultural and the noise of the gears engaging around corners is clearly audible to pedestrians.
I'm more concerned that after cornering there seems to be a bang as the locker disengages.
Its not subtle. At one point i stopped driving, jacked the car up and checked everything for movement with no obvious results.
does rather feel like a 'race only' set up (no corners required!) currently

It's movie time

clickerty clack

clickerty whine

I could live with that, it's only really on tight turns, junctions and roundabouts that it clunk / clanks!!! Proper Muscle car stuff

The 'bang' is not noticeable in the long vid!

one from the outside looking in -

three point clank

thanks Mike


after driving the car for an hour the locker isnt that bad. I topped up the diff oil which helped too the trick is to get on the gas asap coming out of corners and the thing just hooks up. Really chirps the tyres as the last vid shows
Shame about that whiny diff, it being all new kit n'all

Wow that is noisey...seemed noisey goin straight though ?

Steve, the locker is quiet going straight. You can hear the diff...

From their site;
What is the difference between the Powertrax Traction System and the Lock-Right Locker?
While both products offer maximum traction, full wheel differentiation, and easy installation, each product has features and benefits that meet the needs of different customers. The Powertrax® Traction System uses SynTRAC technology and is the latest design in traction adding differentials. It provides the maximum traction of a locking differential combined with the smooth and quiet operation of a limited-slip device. The Lock-Right Locker is our original product line that offers extreme value in a traction-adding differential. The Lock-Right provides maximum traction, but a light clicking noise can be heard when turning as the Lock-Right gears allow for wheel differentiation. On some vehicles the engine noise will overcome the clicking noise. For additional details on the Powertrax® Traction System and the Lock-Right Locker, please see their corresponding web page.

I presume you've got the LockRight then

Yes indeed, it appears I do

currently scaring pedestrians

Even had a Skyline choose not to race me yesterday, probably scared that my car would self destruct with all that noise and damage his paintwork
