Any opinions on using stainless steel replacement bolts for the left axle on my automatic transmission golf? The bolts that came off of it are a ferromagnetic metal of some sort. I see a bit of corrosion on some of the threads on a few of the bolts. The stock bolts are triple square 10mm. The SS replacement bolts are a 10mm hex head.

I thought about using some anti-seize on the threads when I attach the axle.

Am I asking for trouble?

Go for it but I would just buy OEM replacements. They are supposed to be replaced each time. Axles falling out are a common problem because corrosion causes low torque on the bolts and if that happens the cv joint is gone.

Thanks... Just got in from work. I was thinking that I would attack it today. I actually found a left axle from a scrap yard off of a gasser beetle. It's hard to find new aftermarket axles for autos.

Thanks for the tip about replacing the bolts every time. I stripped out the heads pretty good getting the axle out.

Stainless steels usually have a lower tensile strength than an equivalent size steel fastener. Unless the SS bolt was advertised by a very trusted supplier as better i wouldn't use it. Especially with the junk that is available thru most outlets. If you want to scare yourself sometime google "fastener quality act" and look at the good work our government ISN'T doing to protect you.
Use a quality never seize if the bolt doesn't have thread locker on it.

I got the ss bolts from a supplier who provides miscellaneous/hard-to-find bolts, bits, nuts, etc. to the refinery I work at.

Ideas where I could get more OEMish bolts other than the stealer? My bolt guy didn't have anything like the 10mm triple square fasteners. All he had was a similar thread/head size.

I actually got the junkyard axle installed...but now I have a clicking from the same left side that was replaced when I turn left. No noises when I turn right.

I'm not familiar with the assembly your talking about so i don't really know how the bolt is loaded. Allot of times the 12 point heads are used when there is a space limitation which goes hand in hand with a high load application and therefore it's typically a better bolt if it's a good supplier.
I looked quick and a typical grade 8 bolt is rated for 150,000 psi while most of the SS bolts are rated for 70-80,000 psi. I didn't have metric specs handy but you can see what i'm getting at with the strength tradeoff. If you choose to use the SS you should look up the torque spec. for it because i believe it will be lower.
Changing bolt type in a situation like that is sticky business best avoided.

This is what I'm bolting up to. Left side, front drive axle looking into the space where the axle goes.

Agreed. I'll find some more stock bolts. I have to replace the junk yard axle again anyway. :mad:
