Hi guys,

I'm new to this so please pardon the superficial question. I did a fair bet of reading on replacing the front suspension on my 964 but so early on the hands on-part.. I ran into some very rusty screws and ntus. I used a rust blaster but the nuts and bolts are so rusty and they became even softer with the blaster. I think I ruined the screw that hold the ABS wire and the upper bolt the holds the suspension to the wheel carrier. I tried the lock nut end but it too was rusty and won't move!! any thoughts?!!

Many thanks

Keep applying PB Blaster. Use heat. Use impact. Use leverage. Most importantly, use professional-quality tools, and make absolutely sure the tool is completely engaged on the fastener before you start to fire for effect.

Hobby tools are fine for fixing the bicycle, but for high-strength automotive fasteners you need the proper tools. It will be cheaper to send the job to a professional unless you are dedicated and willing to invest in the best tools available.

That last picture reminds me of the rusted Subaru suspension bolt shank I recently twisted off at the threads.
(Rust-fused threads + turd-soft steel + me = killed it.)

If it's a through bolt (i.e., not a pressed in stud) I'd be sorely tempted to high-speed that nut off, replace both nut & bolt, and call it a day.

+1. Your's did not look bad. Think about the restorers of cars from several decades ago, and what a patient and talented lot they are.

Agree with all the above tips. Here is a little trick for removing stubborn Allen head bolts. If your Allen wrench is starting to slip, apply a little oil to the end, then dip in some fine sand.The sand takes up some of the space. This worked for be on a stuck bolt on my steering rack.
