More news from my mechanic: rear beam axle is screwed on the GTI.
Went to the U-pull lot today to get another one... however they have a rule that you can't bring torches or jacks into the scrapyard for safety reasons. But, the rear axle has the rear springs under compression, even with the car jacked up. You have to put a jack under the rear shock mount, disconnect the shock and let it down to take pressure off the spring. Explained this to them, "nope, no jacks allowed"
So I climbed under a '06 Golf TDI, loosened the bolts on each side where the axle attaches to the body brackets... stood way the fuck back with 2 extensions on a socket and took a bolt out.... BANG. Axle hits the ground, severs the brake line on that side, dust everyhwere. Did the same on the other side.. BANG. Safety first!
Didn't get the damn thing out of the car before they sounded the "we're closed!" horn though. Going back tomorrow to finish the job.
