Another OLD BLUE Build Thread - 71 Chevy

[OldBlue71Chevy]

After a full month, I finally pulled Ol' Blue out of the garage and took'er to the car wash to wash the mud off.

Fixed a bang that I had on big bumps. Turns out the U-bolts on the passenger side were too long and would hit my crossmember/bumpstop every once in a while.

All 4 were long, I had already cut one off in this pic. The back right one was hitting the crossmember and the front left one was hitting the cup that holds the bumpstop.


You can see the marks on the two outside threaded portions where they were hitting.


Aside from fixing my front diff breather and re-torquing the steering box bolts, I haven't had to fix anything after the last wheeling trip.




My next project for this week is some shims for the rear axle. It isn't a vibration I can feel, but I can hear the t-case gears chatter some on deceleration. While researching around here, quite a few people said that it could be due to drivetrain vibrations.

The yoke at the trans is pointed down 3* and the pinion is pointed up by 11*. To make them equal and opposing angles, I need to bring the rear pinion down by 8*. This should 'in theory' solve the vibration.

I really don't want to drop the axle and cut off the spring perches, so this is my idea. I have had these 1" lift blocks laying around the garage for some time (years...). I decided they would be the perfect candidate to make shims out of. We have a family friend that has a lathe in his basement so we will be making them this week.
