As moderator for this forum, consider yourself warned. A post like that is not in keeping with the TDICLUB decorum. I may delete the post entirely.
You have come across as inexperienced at car repair at least with regard to the B5.5 Passat.
I also see a person who was anxious to get the car working properly in order to enjoy it and use it.
And then your plans got torpedoed by an accident.
There's a lot of frustration being vented in your posts. I can understand that too.
The advice was to use other available tools to answer some of your questions. TDICLUB is not your only resource although it may be the best. (Yes, I'm biased on that
The standard wheels on a B5.5 in North America is 16 inch size aluminum. 17 inch steel wheels were obviously put on by a previous owner.
The undercoating around the mount points doesn't look disturbed, so that part may be just fine.
Is that body panel separation from the "pinch weld" seam that I see in the left part of the picture on the right? Which side of the car is that?
I'd also check out the shock absorber mounting point on the right side. Also look for any damage to the fuel filler neck area and springs. Is the underside of the body twisted where the shocks and springs are, or will they still be vertical if the axle beam is replaced?
The back end of the car can only be aligned by shifting the axle beam at those mounting points. No other adjustment is available as far as I know.
Oilhammer would have experience in this area.
Here's a general description of the axle beam replacement:
- Raise the vehicle and remove the wheels
- Disconnect the shock absorbers from the beam
- Note the position of the ends of the springs - they have a particular orientation and need to be reinstalled back to the same positions
- Pull the beam down on each side and remove the springs
- Remove the cover piece (if it is there)
- Remove retainers for the parking brake cables
- Disconnect the ABS sensor cables (find the rear wheel bearing replacement thread to see what this is)
- Disconnect the brake lines (Will you be able to reuse brake parts? Brake lines need replacing?
- Loosen the mounting brake bolts (the 3 on each side you took pictures of) but do not remove
- Support the beam and remove the two bolts that attach it to the brackets
- Install the new beam with new bolts to the brackets ensure that the rubber mounting centralizer seats in the mount bracket hole
- Tighten bolts only enough for initial assembly
- Tighten bracket-to-body bolts
- Loosen the beam-to-bracket bolts and tighten only hand tight
- Reassemble the other parts (parking brake, brake lines, springs, shock absorbers)
- Put the wheels on
- With the weight of the car on the wheels, tighten the bracket-to-body bolts, then the shock absorber bolts, then the beam to bracket bolts to their proper torque
- Bleed the brakes
