Hi,
Thanks for the advice
It is a low pinion diff
According to the link you gave the 'drive' side (convex) crown wheel marking on mine is at the extreme 'toe' end of the tooth with most pronounced marking right at the end of the tooth.
That marking is at the crown or top of the tooth.
Point taken on the tooth chips, this is what I am worried about as maximum wear point is right at the crown/toe corner of the drive side gear tooth.
From the same link the "coast" side of the crown wheel for mine shows marking near the toe end of the tooth but interestingly is at the extreme 'root' of the tooth. Not quite the extreme toe end of the tooth so not so bad, but I assume the pinion tooth is running on its crown or tip of the tooth to run that far in on the crownwheel.
So I guess chipped crownwheel on drive and chipped pinion on coast?
Not sure how this miss-alignment is done as one at the top or crown and one at the root require exact opposite adjustment of the pinion vs crown wheel.
So I am not sure how one gets top and foot of gear markings with the one gear set like that but I think it may be mis-aligned pinion bearings vs crown wheel centre line.
Whatever it is I appear to be stuck with it.
If I ever get some axle shafts and can finally fit the assembly I will be able to check what it sounds like.
Note mine is a 5 spd manual so I will hear coast side noises if they exist too.
I note precision gear "ideal" and "competition" contact patterns do not go off the end of the tooth either at the toe or crown or root.
Mine appears to fall into the 'toe' contact and 'high' on drive while 'low' on coast categories.
Here is what I think should be done....
So move the ring gear away from the pinion slightly to fix the extreme toe.
For the pinion....So which is it pinion in or out? Precision gear says both!
Danny at Solid Axle said he wasn't concerned about it. I realise now he meant he has no concern that he took my money and supplied a defective axle assembly.
If you think it is okay... you don't want to buy it do you? Never been fitted to a vehicle, Danny says this is worth $4300.00
Cheers
