Rear Trailing Arm Mount (?) Rust (1 Viewer)

[hysteria357]

Update to this if anyone cares... I ended up just biting the bullet to use this as an excuse to buy a big air compressor with some grinders, an air chisel, and a needle gun. Was able to clean up all the suspension mounts and most of the visibile underbody. Next goal is to finish up the crossmembers. tons of good metal left for the suspension components. Zero holes or thin areas on the mounts. Die grinders are my new best friend. Theyre compact enough to reach above the fuel tank, and using abrasive discs combined with the needle gun I could avoid sparks. Garage now reeks of POR and fluid film. Pretty sure I just bought myself a few extra years.

I might be more concerned about this...
....

Glad you pointed this out. did find 2 rust holes that I was able to clean up and patch. Left unchecked they would have reached the seat mounts.

Hooptie repairs. Took these pics mid repair. They look a lot better now. Going to a weld shop in January to get the crossmember patched. God help me when I need to replace any of the suspension components.

Looks good! Spray some woolwax or such inside the crossmember untill you can get it properly repaired. You may have to strengthen the frame area where the cross member welds up to the frame before the cross member is repaired. Do it right... Once! Good luck.

I'm taking it to a weld shop that does automotive restoration. Luckily, the owner said he has fixed the same spot for cruisers before.

Unfortunately it is a very common repair on these beasts... our shop cost to the customer for this repair varies from 600 to 1500, depending on severity and how much fabrication is needed. We also complete the repair by cleaning the entire spare tire well, acid wash to neutalize the corrosion and oxidation, then prime, paint, hard coat the exterior frame and soft coat the internal frame and cross-members. The spare tire comes down, the rear spring is removed and such...
