Rocky Road Spoa Lift Help (new guy)
« on: January 24, 2008, 06:44:14 PM »
I had my axles welded at a shop and they were supposed to weld the front  Pads perralel to the bottom, and the rear the pinion is 3 deg. up     When i bolted them up, the rear looks level and the front is pointing upwards at a steep angle, is this normal?

No, not normally.  On mine they are both pretty much level.  Did they leave the lower spring pads on or did they cut them off?

Call Rocky Road and ask if there is a difference between the front and rear SPOA perches, then measure what you have.  HTH

Did they install the perch backwards, meaning the front of the perch was installed towards the rear?  This would screw things up a tad bit.

Park on a level surface and take a level to the lower pad.  It should be even with the ground.  :)

thanks... ill try that, also i bolted the front driveline on no prob and the rear wont go on unless all the way extended!!(with spacer)  so i think they might have put the pads on backwards.

Not necessarily.  I didn't need to put a spacer on my rear drive-line, neither did one of the Sammy's in the club.  I didn't need a spacer until I slid the front axle forward.

what does your pinion angle look like, mine is flat so thats got to be the reason it wont hook up?  I was thinking about 3 degree shims.  how far is your slip yoke extended?

I'm not saying that a spacer isn't needed, just sometimes it isn't.  I think it depends on your pads and how much arch you have on your springs.  My pinion angle is pretty much flat front and rear.

The proper way to fix the problem is flex out and re-size your drive shaft properly.  The spacers just easier.  :)

Hi:

The new SPOA front axle perch spring faces are supposed to be exactly parallel to the faces of the OEM perches.   If you plan to drive this truck on the road, it HAS to be this way.  Changing the pinion angle like that will seriously mess up the caster angle and make the truck hard to handle on the road.

Also, unless I am mistaken, the passenger side front perch is specially cut to fit on the sloping edge of the dif housing so it will line up position-wise with the OEM perch.  That's the way it was for my Breeze SPOA.

Check out the following links:

I'd take the axles back to those cowboys and tell them to reweld them parallel for free - unless they want to buy you a Double-cardan driveshaft and cut the knuckles to fix the caster problem for free... 

BTW:  Didn't the perches come with installation instructions?

Not sure if you will get this but.... Are the rear pads suppose to be welded parallel like the front? Or should i go 3 degrees above that?

I would just go parallel, just like the front.
