Just fitting merc back axle to Xj and was wondering what the reason for fitting shocks one in front and one behind rear axle is ? :017: Can I just mount them in the behind position with no detrimental effects ? Thanks.

I can only think its a nod to some sort of axle wrap control..... But then they do it on TJs as well and they got no leaves to wrap.......
I'd go for it as I always thought it daft and that they should be in front of the axle :icon_super:
-
double your chances of getting it right, fit twin shocks one pair in front and one pair behind :icon_twisted:
-
Front it is then,thanks for the info :icon_biggrin:

I don't wish to contradict but it's normally the rear edge.
Why not mount it like the Toyota's pointing inbound - lots of flex that way? Just bouncing ideas.

Lol,very good. Now I'm confused,what would be the difference front versus back ? While I'm here and talking rear axle,would air be capable of holding dogs on diff lock that whas ment to be hydraulic ? It operates it fine,just not sure it would hold them when giving it a bit of pain ? :icon_twisted:

Just look at the ark and decide what is best for your application.
-
As long as you have a DAMPER at each end of the axle point vertical theres no point redesigning the ark. They are there only to stop axle patter driven from road bumps

GEEK MODE ON:
They are actually aranged that way to help with twisting of the axle and in the event of tire spinning they will help to subdue some of the "tire hop" that may happen. In a properly set up rearend there shouldn't be any horizontal movement seeing as the axle is bolted to a specific spot on the springs. Also it helps to stop some twisting if one side of the axle hits a hole the the other doesn't. if they were both on one side the axel would tilt or "twist" and could possibly damage your universal joints and cause major problems.
To prevent axle hop especially on washboard surfaces. Leaf springs are prone to hop.
If the shocks are mounted on the same side of the axle the springs 'cycle' because of the mass of the axle and the road's impact at the same time at each tire.
There are two solutions:
Increase the shock's damping and the overall ride suffers or
Decrease the damping and install on opposing sides of the axle for a smoother ride.

gave it serious thought about using that picture but it wasnt the appropriate choice
