2015 Ram ProMaster 1500 3.6L (ERB) 6-spd (62TE)

Trying to get the rear toe perfect on this thing (Hunter Hawkeye Elite) and it has you loosen the U bolt nuts and "shift the axle" as needed to get it in spec. Im not seeing where I can get a pry bar in there or any other leverage device to shift it especially with shackles and a shock holding everything rigi. I tried hitting the axle beam but all that does is make the readings go nuts because of the vibration from hitting the axle. Anyone run into this?

Did u loosen the nuts of the Ubolts? I seem to remember the plate having elongated holes so u could shift the differential. I'm pretty sure it was a promaster. Back the nuts off enough to look at the plate and see if they're oval.

Yes, they were loosened. Not a great pic but this is what it looks like.

You can use a power puller/come along around one end of the axle or the other to get the movement you need. Just get the U-bolts good and loose. Take care where you connect the other end to the body or frame, of course. It shouldn't take that much tension to get things moving.

...Might have to use a high speed burr in a die grinder to alter the holes so it can be shifted. ...Dan H. ...South Texas...

Once you get everything loose I just put a porta power in there and pump it up. Let the hydraulics do the work

Wait a minute........ are you trying to adjust rear toe or thrust angle? With a beam axle, you’d need to bend the beam to alter toe. Moving the axle forward on one side and backwards on the other will adjust thrust angle but won’t change toe.

...Sounds like a new beam would be in order...one that isn't futzed up...Maybe some selective shims behind the bearing hubs ,if design allows. ...Dan H. ...South Texas...

I have not done this exact vehicle, but have had similar issues. The porta-power is a good suggestion, but with that Hunter Rack I have used ratchet straps too, the porta-power is kinda overkill and not as fast. I use the cutouts in the lift for the step to hook into and then attached to a part on the car. Sometimes you have to lock the table and not do it with live data though...

Not sure about the toe on this, but sounds like he is trying to shift the axle. I use the straps to shift cradles and other things, figured it might work, been wrong before though ;-)

You have a box channel above and an axle tube below, quite simple to stick a pry bar in there and get it done. I will not help toe, though. This makes no sense. Just because the machine says so, doesn't mean it is right.

How far out of whack is the toe? Judging by the alignment instructions in Alldata this isn't going to be like fine tuning toe on a tie rod equipped vehicle. The directions read to me like, get it as best as possible looking at both sides at the same time-you can't affect one side without affecting the other. If your toe is way out on one side and the other side is in spec., then I would say you…

It is almost a half degree out.

So you are saying you are 1/2 degree off of the spec of Total Toe of 0.4° +/- 0.25°? Can you post up your actual readings in an image? I haven't done an alignment in about 12 years so my memories are a bit hazy but I think 1/2 degree translates to about 1/4". I'm not sure how well aligned these things come from the factory-are they normally spot on, or were they built poorly and never in…
