Default Half shafts play

The right side axle has some play left and right

The left side has no play

Transmission has a guard lsd - is this normal?

There are bolts that hod those splined shafts to the diff - you may want to check and see if they are both still there

Here is a breakdown of what is there:




The LSD's can fail at one of the necks - but then the car would not move. Without a little more investigation, I would not be able to tell

Knowing how the lsd goes into the housing, my guess is #10 on the diagram is lose on the side shown in the video with the play but still in enough to move the car. Look into it some more, and probably wise to replace some parts.

Good point Redmonkey,

Gptoyz, the bolts I was referring to are the 2 that are visible when you pull off the half shafts, not the bolts holding the half shafts to the flange. They are usualy torqued to ~ 35lb-ft - although I would check.

If you need pictures I have a lSD on my bench and could take some pictures.

+1 pull that half shaft off of the flange and check the center bolt on the flange.

Hey guys thanks for all the responses

So the half shafts were pulled, the bolt was still there and present however it was the factory bolt

I spoke with Matt from Guard this morning and he indicated that the installer re-used the factory bolt instead of following the guidelines of using a +5mm longer bolt

Incase anyone else needs to check their LSD here are the specs of the center bolt:
Factory M10 x 85
Guard requirement M10x90

Then that may not have been the problem. Those bolts snug up the flange axles to the diff. If everything is installed correctly there really isn't any play. At this point I would take the diff cover off and look around. Once you move a few things out of the way, pretty easy.
