Drilling through a leaf spring is no easy task. I had my leafs out when I did mine so that made it easier. Doing it under the rig sounds like a nightmare.

Normal drill bits will not cut it. The spring steel is just way too hard. I used masonry bits that I picked up at Lowe's. They were dull after drilling just two holes but did a great job of biting into and removing that real tough steel.

 

Just made a trip to HD about an hour ago and picked up a couple of cutting discs for my angle grinder, two 3/8 carbide masonry drill bits, and some cutting oil. I have already done some research on this and learned that the masonry bits work best. I plan to go slow and use lots of cutting oil. Might be starting the job this weekend so wish me luck.

 

Here's to you. Good Luck. Happy Jeepin'

 

Just an fyi, carbide likes to be run fast and kind of hot.

 

I started to work on this project today but after starting to jack up the rear end, I found that my driver's side frame rail is in much worse condition than I had originally thought. Here are some photos showing my dilemma. The jack stand in the pictures does not even have any weight on it because the frame rail started crunching as I was lowering on to it. I'm thinking that I have a lot bigger issues needing resolved (if even possible) before worrying about the leaf springs.

 

You let it get out of control man haha

Holy Schnikes! I though my rust was bad. Yours is Titanic-style, cannon at the bottom of the harbor style. Good luck.

 

I'm sorry man but....that thing is trashed. Save the parts you can for your next jeep, that one's history...or should be.

Best Wishes to you and RIP Jeep.

 

Not sure what looks more scary, the frame rail or the drive shaft.

 

Right? It looks like the driveshaft for a propeller on a submarine from WWII.

With that angle they should have installed an SYE!
