Replacing driver side axle. On re-installation what are the bolt torque specs and do I torque in a star pattern. Any other advice that may help would also be appreciated. Thanks, Wayne

30ft lb. Star Pattern. Clarks-garage.com! I like to go once more around after the star.
I drilled all mine and safety wired them.
Check them after a session or two on track if no safety wire.

This is the best information I've found on the topic:

For fast changes and retightening I like using an electric ratchet. Saves a lot of time!!!!

If you can't safety wire them, put a dab of paint or nail polish on the bolt head and dog bone so you can visually see if they've moved. Check them after each of the first couple sessions.

Be sure the threads are free from grease. As Sid mentioned, an electric ratchet is really helpful for this.

I did not have any Schnorr washers when I pulled the axle out. Just bolts and moon plates. Is this normal? Thanks for all of the good info guys.

These bolts are designed to be used once and then replaced. Although many on this site including myself have reused them. If you do reuse them check the torque regularly until you have confidence they will stay put.

I have cleaned my bolts and bolt holes with brake cleaner and they have backed out. I am glad that you have had a different experience, but they will back out once used which is why people go to extraordinary lengths to insure they do not.

Just went through this as well. Bolts back out a lot regardless. Used stage 8 kit and so far so good. Drilling and wire works to if you are able to. Had to repack grease frequently.

Is this due to the power output of the 951?

I race a 924S and never have issues even after 24 hours races?

I have just finished the rebuild of a street/track 951 that will see extensive track use -- so I'm even more interested.

thanks,

Here's how I keep mine from backing out.....

Over tighten the crap out of them. Yep.

Like... Take the torque wrench and shove it up your @$$ so you don't pop a hemorrhoid while tightening, and then use a godzilla sized 3/8" ratchet and just tighten like a mad man until the bolts are on the verge of stripping out.

Then go do some burnouts and stuff and junk.

Works every time. Dang, my DIY should be on clarks-garage.

I think part of it is how you use the car. Mine is a track car only, and I end up changing CVs every couple of years. My car produces around 400 ft-lbs torque depending on outside temp. I have a solid transmission mount that may have something to with my bolts backing out, vibration etc. I found that the bolts seemed to stay torqued better if they are new. One of my daily inspections at the track are the axle bolts.
