So it's been about a week since the last update.
I got her all buttoned up and got her on the road. I've been breaking in the gears, and I think that it is going okay. I don't like some of the noises I'm hearing, but waiting till after the 500 mile break in is over to investigate if they keep persisting. I just finished this evening at 250miles, and have been doing about 50miles a day. I think I am gonna cut that back a little bit, and probably stay off the highways after this evening.
I had been running it just in 2WD for the 1st 100 miles and now have incorporated the front differential as well. I drove it in 4wd for about 15 miles at about 35mph for the 1st run last night. Tonight, I ran it for about 25 miles at highway speeds (< 60mph). The rear gear set is sounding quite smooth by now, but the front still has some rough gear noise. I am also having that 4th gear frequency oscillating vibration between 45 and 60. I am wondering if my front drive shaft has a bad U joint in it. When I rebuilt it the last time about four years ago, I remember not having enough U joints to redo the axle mating joint. I just rebuilt the double-cardan joint, and left the last u joint in place. I am hoping that the majority of my bad vibes are from that u joint. I have them on the way from Rock-auto in the morning. Regardless, the vibration is still there(not as prominent as before), but I think it could be coming from the front DS and not the OD unit like I had been thinking. The angles on the front DS and the rear DS are less aggressive(?) since changing to these axles. In an attempt to quelch the bads vibes, I'll be changing out both rear DS joints, and the one up front: Hopefully, that will stop the bad vibes.
I will be posting up pictures of the final result of the frame stiffening/plating eventually, for I just haven't spent the time to snap the photos.
All in all I think I am breaking in the gears correctly, and I have been feeling the temps of the diff housings at the end of the 50 mile run every day. They have never been to the point I have had to take my hand off of them because I would have gotten burnt. (I have a high tolerance for heat thanks to the cooking profession) Although, I have to admit it might have been that hot in the diff. I don't think that the internal temp ever exceeded ~260*F. However, I would venture to guess the housings were probably in the 110-155*F temp range when I am feeling them at the end of the runs. I am guessing that the internal temps would have been in the 180-220 range. I am not sure at what temperature GL-5 Gear Oil breaks down at. I could be wrong, but I am of the opinion that most motor oils burn at around 300*F... what that may equate to in a gear oil I am not certain.
If there is something glaringly wrong here, please say something.
After I get some pictures of the frame plating, the wrench-a-thon continues and then on to: the rocker panel replacement, door rust mitigation, ABS controller repair, and the sun roof track repair.
