Hex Head Bolt And Washer - Mopar (6507538AA)

That fits; Toe Link, Right - Mopar (68051638AB) or Toe Link, Left - Mopar (68051639AB)


When adjusting rear toe, the eccentric lobes on the toe adjustment cam bolts and washers are not to be facing downward. The lobes should only be facing upward, or up to 90° to one side or the other from the 12 O'clock position.

1. Loosen the cam bolt nut securing the toe link to the rear crossmember (front of rear crossmember) just enough to rotate the cam bolt.

2. Rotate the cam bolt head on the opposite side (rear) of the crossmember in either direction until the preferred specification is obtained.

3. While holding the cam bolt from turning, tighten the cam bolt nut to torque spec (80 ft. lbs.)

4. Adjust rear toe on opposite side of vehicle using the above procedure.


Once rear toe is set, set the vehicle's front toe.

based on my current alignment before adjustment do you think I need to buy some parts to do this alignment? Do the instructions above apply to my current situation?

It is so strange. I am pretty sure it is adjustable. But Mopar could be saving a buck and eliminating them?

We don’t know. BUT, one of those alignment guys should be able to tell you that in minutes (if you have the eccentric bolt in the rear).

Someone screwed around with your front? It was more than reasonable before, it sucks now. They got the toe way out now, and somehow managed to change the right camber to much more tilted negative. The rear seems fine. I’m out, dude.

something must have happened from December 2019 until now, not sure if it's pot holes, curbs, or something. Don't think I hit anything major, hopefully my mechanic can find a good fix. A while back I could have sworn the bodyshop took my car on a long joyride, hoping they didn't permanently damaged the frame or something effecting the alignment, if they did maybe it should be obvious when lifted hopefully

Have been doing alignments a long time and can tell you that subframes have been shifting around under cars since the day they started bolting them under uni-bodies. Pot holes, curbs, pavement edges, and even aggressive driving will shift them. And all Mopars with suspension system they've shared for last many years do not hold alignments well. Just too much going on. Recommend yearly alignments after rough winter season.

Was taught to us years ago that a 1oz imbalance on a 15" wheel at 60mph was the equivalent of an 8lb hammer striking your suspension and steering every revolution. So how much force do you suppose a 4000lb car hitting a pothole while entering a parking lot at a 30deg angle at 15mph can impart on the subframe which is only held tight by 4-6 bolts? For the extra $30, have the shop shift the subframes first to get camber angle and caster lead as close to perfect as they can, then set both rear and front toes to get proper thrust angle and toe setting. Alignment that is close is fine, but alignment that is as perfect as possible can be felt and will hold proper "feel" longer.

And camber definitely can wear tires. Toe wear results from tire scuffing while camber wear will result from unequal load across tread face.

All this alignment stuff sounds a bit confusing to me. I think the mechanic may have said something like start with the rear then do the front or something. I also thought it wasn't a good idea to shift the sub frame or something. To get it to be exactly right don't you need upper control arms for the front and camber bushing for the rear or something?

unless you wanna learn how it all works (which is sorta hard without actually working on it yourself) you are probably best off picking one guy that you trust and having him do the work

looking at your printout i do not believe that guy will need any parts to get it right

First i'm wondering are these instructions for fixing alignment issues on my 2017 Dodge Challenger Scat pack (dynamic package)? Is there a link to this document? Should I just forward this to my mechanic that is hopefully able to work on my alignment if his machine is back to being working tomorrow?

If i'm understanding correctly:

The camber and caster are not (normally) adjustable angles. I'm assuming these are referring to the front ones? So you'd have to shift the engine cradle first using the instructions on the document pictured below to adjust the front camber and caster, is engine cradle another name for subframe? However if that doesn't work (not in specification so in red) then you may buy a service adjustment bolt package.

If rear camber is not found to meet alignment specs, repair camber links are avaialbe in plus or minus one lengths. It seems my rear is not too bad as it's all in green. So it sounds like I may not need to buy any parts for the rear?

Possibly only the front if shifting the engine cradle won't solve the issue?

Where do these DODGE CAMBER/CASTER ARMs come into play if ever? https://www.jegs.com/i/SPC/827/66047/10002/-1
Could anyone confirm the service adjustment bolt package being referred to in the document? Is it this? 6507538AA - Genuine Mopar Bolt-HEXAGON Head or something else?

I was looking at this post Engine Cradle Alignment and someone said there was a 10 page document of the alignment procedure. The link doesn't seem to be right. It doesn't have an option to go to suspension and then alignment for the document access. I wonder if anyone has a new link to it. Trying to find the instructions Mopar would use so I could give the right instructions to the person doing the alignment

If shop doing alignment doesn't already know how to perform procedures required to align your car properly without your instruction, I'd recommend finding another shop.

Alignments are almost an art and person doing alignment needs to know all proper methods, many self-found tricks, and MANY alignments under their belt if they are going to do a professional job.
