Project Yellow Basket: Frame Repair Questions

Project Yellow Basket (Formerly Yellow Jacket) is starting to progress now that I have freed up space in the garage to proceed...

As this is my first rebuild project I have a few frame repair and rebuild questions for the board.

My end goal is not to restore...but to rebuild a solid Jeepster as fast as possible so I can have a solid hunting and fishing vehicle at our place in Montana by spring 2005.

As salt is used on the roads, I would like to try and protect both the frame and body from corrosion as much as possible.

I have two jeepsters currently stripped: A '70 and "67 both in rebuildable shape with all the parts in fair to good shape.

The '70 I have had since 1980 and moth balled it in 1996...the 67 is a receint purchase. I have decided to rebuild the first jeepster using the 70 frame as it has power steering and fewer frame repairs than the 67 frame. The '67's body/tub is in a bit better shape than the 70's tub and was hacked up a bit by the previous owner.

I am a pretty fair fabricator/welder.

- The rear cross member on the 70 frame is a little beat and has been weled on and I had a welder weld some gussets from the frame to the crossmember some 20 years ago...The rear frame cross member area is solid but I would like to replace the cross member or beef it up with some 3/16" TO 1/4" channel iron for a future tow hitch any suggestions?

- One of the rear shock mounts blew out of the rear frame along with a 5"-6" top section of the frame. This looks pretty bad but I think it is fixable. Any suggestions?

- I would like to box in the open frame in the rear frame section. Will 3/16" plate cut to the inside dimensions and weldeded in place work? Should I consider drilling hole in the bottom of the frame rails, welding nuts in place for future tow hitch attachement points to the frame?

- The frame has a fair bit of surface rust. Per a local paint company reccomendation, I have pressure washed the frame to prep for rust conversion...the paint shop reccommended Rust Mort or Marhyde rust inhibitor products followed by good qaulity frame paint. Any reccomendations in this area appreciated.

- Body Lift: I can easily fab some 1"x2" DRILLED square tubing riser blocks and weld these in place over existing body mounts. Is this preferable method over using existing mounts and higher pucks?

-Are there specific areas I should check for frame cracks?

Responses and reccomendations appreaciated!

On the body mounts I would suggest using thicker pucks instead of welding on the tubing.You want some flex in there so as not to rip the mounts out of the tub.And on the frame painting I highly suggest POR 15 chassis paint.It is a bit exspensive but seals out the rust and is hard as a rock.Very hard to chip,you can beat it with a hammer and not chip it.If it is applied correctly.With the salted roads it would be a good investment for the Jeepster if you plan on keeping it around.

All though winter can be hard on vehicles, I dont think you have to worry about salt on Californias roads. I belive they did away with it and use a pretty much sraight sand mix. The enviromental impacts of salt are just to damaging. It completly changes the PH of soils and streams, plus makes it into are drinking water. So hopefully this helps with your salt questions. I know Toulumne county doesnt, its really easy to contact the county and ask. Good luck

Here's what we had to deal with on Punkin. After the 30+ gallon gas tank was removed, we found major frame damage in the rear. The tank was so big that it hid the damage on initial inspection for purchase. Here's the rear cross member.

Thanks to Ryan, "The Jeep Guy," who supplied us with another frame. We decided to improve on its' design before putting the body back on. The good thing about the Jeepster's frame over the CJ's of the same era was that the Jeepster frame was boxed while the CJ's were just C channel. But the Jeepster stopped short and used C channel from the rear frame rails aft. Here we plated up the rear cross member to make it boxed.

We then cut off the rear frame rails on the old frame. The old right rail was used to box the left rail of the new frame and the old left rail was used to box the right rail of the new frame.

Tim posted pictures of some great work. We have not done a frame off yet, but I did reinforce the rear crossmember on Ole Yeller as follows;

1. Remove rear body mount bolts, middle ones and leave only the front ones on.
2. Jack up the body from frame about 2", there is enough give to do so.
3. Use a piece of 4" C-channel and cut/fit over existing crossmember middle, extend to outer side of frame rails.
4. Cut holes for your bumper/hitch/etc. in the channel.
5. Put it in place, clamp and weld er up!
6. Paint, lower body, reinstall old or replacemenmt bolts, reinstall bumper and viola; strong crossmenber!

You can just see the channel in this picture.

Brad.
