You tried the plastic shim and it failed I'm not understanding that? The shim didn't fail I guess it's do far out . ? So then bending it back is it .,? The manual say no adjustment . So maybe the manual was written before they made shims I'd be interested to know which way bad,? You had too much neg camber do it got towards 3 degrees would be worse if it went towards below the 2 degrees it would be getting better . So the shim at max isn't enough to bring it to spec it seems . I would love to see the scan of your alignment of getting worse .
Seems to me you be trying to pull down on the beam . Which you might do with long iron bar in the bearing hole . Or plate attached to lugs .
WE HAVE SUCCESS!! I went to my local yard picked up a replacement axle while there I did the corolla rear sway bar upgrade. installed the new axle pretty quick like 16 bolts total will need a grinder to cut open break lines holder it has shims to hold it in place like traditional lines. reinstalled and had it aligned. Side note only two 17mm nuts attach your rear axle to your car should be 19 IMO. .
Glad that it is fixed. However, I am now even more confused. The alignment shown in post 23 has the alignment problems in the front, whereas the one shown initially had them in the back. In the most recent alignment shown here the difference in the rear before/after is about what would be expected for the same car (the numbers never come out exactly the same from one alignment to the next.) The front alignment changed though. But the rear was changed? Are you saying that after the rear components were replaced you took it in to the alignment shop and somehow the alignment problems were now all in the front (before section), but within adjustable ranges, and so they fixed those (apparently without touching the rear at all), and that is the final? When the old components were off the car, and the replacements not yet on, did you compare them to see what was bent? Or was the damage too subtle to spot by eye?
Sorry, I didn't see this post. In the Glock all the parts that are mechanically stressed are metal, and those are fixed in a tough plastic frame. I'm pretty sure that weapon has been carefully engineered so that the plastic pieces are never stressed excessively. The shim shown in that video is sandwiched between two solid pieces of metal and will be subjected to varying compression forces as the car moves. That is a pretty good recipe for making powdered plastic (eventually).
But if think that mite take a real. Looking time.. years under car no sunlight but heat and toad grime.
