1) Nowhere in the manuals, nor did folks mention, to be sure that when assembling the rear axle/tube/tension nuts/oscillating arm - to be sure to go to the car and remove the little L-shaped brake cable/hose bracket:
>> it needs to go ONTO the pinch bolt before you put it all together and set the correct "gravity-drag" for the oscillating arm.
So lets say you did all the setting up of the assembly , and put the correct tightness with the axle tube/flange and the oscillating arm....and say you DID forget to put the L-shaped brake line support under the pinch bolt.:
QUESTION: once the nut at the bottom is loosened, should the pinch bolt come right out, or is there (supposed? to be / sometimes there is??) some sort of side-tension on the pinch bolt being applied by the double-nuts & cupped spring washers?
Here is why I ask: with the frequent mention of a special tool that gets threaded into the M8 grease fitting hole at the end of the axle, I (apparently wrongly) thought that it was meant to relieve some sideways "pull" by the U-channel in the axle end, caused by the cupped washers and double nut tension setting. But after setting my oscillating arm tension exactly correctly so that it would stay at 3 oclock horizontal unless helped downward and installing the axle into the body tube and driveshaft carefully into the trans - thats whrn i discovered i had forgotten the brake line bracket goes under the head of the pinch bolt.
Now i was worried, because i didnt have the tool that i could have sworn was needed to help relieve the side tension, to be able to remove the pinch bolt without scoring it upon re-insertion. I quickly looked in the Maint Manual, and saw an AC15 U-shaped puller-bracket tool in a pic.] So i went to home depo to make up a DIY tool that would screw/nut washer into the greasefitting hole to help relieve any tension.
But before attaching my new contraption, i tried the nut and pinch bolt...and lo and behold: it came right out - there was NO side force to even RELIEVE.
Im frustrated and confused. First, the manual doesnt tell you to remember that goddamn bracket.
...Second: am i crazy? -I could have sworn i remembered Gord or someone saying you need some way to relieve tension on the side of the pinch bolt , or without the tool, the u-channell wouldnt line up, the bolt would be not only stiff to remove ...but the sharp edges of the axle u-channel will scounge the bolt going in, creating rough scars exactly where it wants to seat smoothly in the channel when tightened..
So, is the pinch bolt supposed to be able to just pull right the f. out after the back-nuts have been tensioned per instruction? (Actually tensioned even a little tighter - 1/2 turn instead of 1/3)
Then i went to the manual to read more carefully about the AC15/22/2 u-bracketand threaded bolt/nut/washer contraption, and although it mentions using it to help pull the axle INTO the oscillating arm (for folks that didnt go all they way and remove the axle to set the tension, etc) - but i cant find it mentioned to use that tool to relieve tensioning side pressure on the pinch bolt to prevent scoring it. Am i dreaming?? Please clarify!
i dont want to introduce "play" with a defective understanding of the forces that need to be correct - and that u-channell edge is awfully sharp and even cuts into grade 12.9 bolts easily.
(see other thread for that info)
