Spring is finally here! Oh, and rocker install.


Edit:
I had to remove some pictures as I submitted a replacement procedure for the rocker to CJ Pony Parts.  You can see them and my write up there. Complete Rocker Installation



  This has been a really good week for me.  I have had three full days of 50 and 60 degree weather with which to work on the car.  So out comes the tools, and back to work on the car.  Now for those of you who remember what it was I was working on, it was installing the new complete rocker assembly on the drivers side.  I had run into some fitment issues due to the fact that the replacement was a slightly different size than the original.

  The problem areas were the a-pillar where I had done a patch using the original rocker as a guide, and back on the b-pillar and quarter, where I also had done a patch.  After having three plus months to think about what needed to happen in order to get it to fit, I had come up with a solution.  It wasn't one I was really happy with due to the fact that it meant cutting out some of the work I had done and redoing it.  Problem was, I couldn't figure out a way of getting things to work properly without doing it that way.

  After pulling everything out and get the rocker fit up into the panels, I had confirmed that things needed to be redone.  Sigh.  So out comes the old whirling disk of metal destruction, and out comes part of the patch for the front a-pillar.  Suddenly that part of the rocker slid right into place.  All set there, now to head to the rear.  Now at the back, there are some tabs that stick out that were flush with the old rocker. they are on the inside of the b-pillar brace.  The original rocker was a little bit shorter than the reproduction piece.  The new piece had more metal in the area than the old one.  To solve that problem, I simply cut a couple of notches for the tabs to fit in.  Suddenly that bracing piece slid into place between the inner and outer pieces of the rocker right where it was on the original.

   Now onto the quarter fitment.  The problem with this was that I had welded in a new piece because the flange at the bottom had rusted away.  Somehow I had managed to weld it a little low towards the back end.  I had based my patch off of the piece I had cut out.  I didn't realize that the back side had been sloped down about 1/8 of an inch.  Every time I went to fit the rocker there was a gap at the front and it was flush at the back.  What was the solution?  Basically do a relief cut almost the whole way up the piece so that it would shift enough to get everything tight for the quarter/rocker gap.  Out comes the wheel again.  Cut is made, and everything now fits.  What is the lesson learned from this?  I should have replaced the rocker first, and then welded the patches in.  Hopefully I won't have to do this type of thing again.

  Now before I welded everything in, I grabbed the wire wheel and the wire brush and scrubbed out the areas that I wouldn't have access to again and then sprayed them with zero rust.  I fit everything and lined it up, donned my new auto darkening helmet from Harbor Freight (on sale, by the way), and started in on the welding.  Holy crap!  My welds magically improved, I wasn't blowing through as much, and I was welding a whole lot faster!  Why did I ever think that a regular helmet was ok, I will never know.  I will never go back to a using one of those things.  Little tip for anybody not already using an auto darkening helmet.  Go get one right now!  I still need to check the door alignment and grind down the welds, but it is in at last.

  My next post will hopefully cover the rest of the torque box, and getting the toe board in.  With any luck, my repairs will start to happen a lot faster as more of the structure is replaced with good metal.  On to the pictures!

Here you can see where I had to trim my patch back.  The welded metal  just wasn't flexible enough to reshape to the slightly different size of the new piece.  I'll have to put a new piece in.  There was also a little surface rust where I didn't get it properly protected before winter.  It came off easy enough with my wire wheel.


Getting it tight and flush.



The relief cut I had to make to get the rocker to line up all along the bottom of the flange. :(

Here is that cut again.  Notice how the gap is flush and tight.  All that gray is weld through primer.  I  ground down the e-coat and applied the primer.  I don't like to leave any untreated areas if I can help it.

You can just see the two little tabs that stick out on the brace that is slid in between the two pieces of the rocker.  I had to cut notches so that they would fit where they were supposed to be located.  I sandwiched it all together before pulling the weld trigger.  I love my high clamping force clecos.

Everything is fully welded in.  Time to get that brace out of there.

  1. Nice work Grant! Sometimes a "cooling off" period helps bring things into perspective. ;-)

    1. Or it gives you time to realize you made a mistake, rage over it, think it through, resign yourself to action and finally resolve all conflicts. :)

  2. Glad to see you back at it again Grant. Sometime that time in between working on the car can help solidify the plan, even if it means doing a little back tracking. But you can't deny the results! Nice work!

    1. Thanks Dennis. Once I figured out what the problem was it just slid right into place. Sometimes you do have to move backwards in order to move forwards. I think we all have done that at some point.

  3. Great update Grant! I have learned to purposefully give myself a "think" period on all of the "big" jobs these days and have never regretted it. GNice to see you are back at it! Send some of that "Spring" stuff out here!

    1. I'll see what I can do Sven, I don't think I want to give any of it away though. :P
