I use multi duty, complex, high temp grease, that comes in a tub from the auto supply or walmart for about $4. I keep a can around for many different purposes, like keeping the ants out of my hummingbird feeders!
1. What size Allen wrench do I need for the front axle nut?
One thing to watch for keep in mind if you are going the socket route with 3/8 extension inserted backwards or from the inside...a lot of 13/16 sockets now do not allow you to do this not machined right through so check before you buy...also I use Honda Moly and wheel bearing grease as the high temp. For wrench I went to local bolt supply found 4 inch long bolt that fit perfectly and two nuts locked against each other put breaker bar socket on nuts worked great....less than 2 bucks if you want to get fancy tack weld the nuts to the bolt.
Ok, my search skills didn't quite find me the answer, so here goes.
1. What size Allen wrench do I need for the front axle nut?
2. How do you get those pesky brake line loops/brackets off the front fender?
3. What's the best choice for the "high-temperature grease" and the "molybdenum disulfide grease" when re-installing the rear wheel?
Pulled the rear wheel for the first time, took all of six minutes. Spent 12 minutes to get the front wheel to the point that all I need to do is remove the front axle and pull the wheel. Would have been quicker, but one of those front caliper mounting bolts was a real .... um .... pain to break loose.
