I just installed my locker for the second time with the stock 4.10 gears and just like the first diff it clunks when I let the clutch out and shift. I checked the B/l like 4 times in 4 places and got .006 - .007 all the way around every time. This is a 85 toyota. Its an aussie locker in the rear.

Get a new housing--its bent...
 
Get a new housing--its bent...

I was gonna say "normal"... IMO as long as it's locking up properly, an autolocker can make all kinds of noises and I don't consider it something to worry about... because they make lots of noise, especially with a manual transmission... But it's worth at least checking the housing for straightness somehow.
 
I have a detroit in my 8.8 rear end on my Jeep. It turns an easy 1/4 turn before it engages the gears.

When I had a bent housing on the D30, under power it made a "POP POP POP POP" sound. A highly unmistakeable noise. Like someone was hitting the diff with a hammer repeatedly. It totally trashed the locker. But you couldn't mistake that sound, it was severe.

The rear locker sometimes "clunks" once under power, when the torque load shifts. But I know that to be okay now. It did scare me at first.

If it makes a continuous "bad noise" it is time to inspect.
 
Its not continuous its just the pinion turns more then it seems like it should. Its not a popping noise its just a clunk when the slack is taken up by letting the clutch out.
 
Would a bent housing explain why my pinion flange turns so far each way before it stops?

No thats normal.

Whats hapening is with the housing being bent it causes the side gears in the aussie to kinda side load verticly--and thats what creats the pop. Have seen it a # of times....
 
If I remember right with my old lockright I could get about a 1/3 of a turn out of the pinion before engagement...with my detroit it is much less.
 
throwing out a way stupid question but i thought id check, are the rear tires the exact same size? same exact tire and wear?
 
To determine tire size you should do a rolling circumference test.
Air all 4 tires up to exactly 30 PSI. Use a good gauge, not a pencil type cheapy. Take chalk and mark down the sidewall and onto the pavement. Roll the rig one full tire revolution until the marks hit the ground. Mark the ground and measure all 4 marks. Put the 2 tires most equal on the rear axle.
