Does your Mitsubishi L300 make a strange noise? Need wheel alignment specs?

Replacing leaf springs, impossible to remove!

Postby Mr.SA » Thu Jun 14, 2018 3:37 pm

We’re replacing the leaf springs on my l300, we got the rear shackles removed, u bolts, it all came off fairly easy. everything except the front bushings, the oval shaped ones. We have the nut off but the bolt won’t budge. Spent probably 7 hours on them using a big impact on the bolt, a ton of leverage, tried a blow torch, etc. and now resorting to a sawsall which isn’t doing much to cut through the bolt.
Anyone else had this much trouble? There doesn’t seem to be much corrosion or anything that’d be causing it. Any tips from someone who’s done them would be much appreciated.

Wow, that sucks. So the bolt won't turn at all? It's frozen to the steel tube inside the rubber bush?

That's a class 10 bolt, from memory, so a sawzall with a *really sharp* high quality blade should eventually cut it, as long as you don't let the saw teeth overheat. If you can cut the head and tail off the bolt (angle grinder? There's not much room though) you can probably tilt the leaf enough to get it out.
Nothing says "poor workmanship" more than wrinkles in the duct tape.

Your best bet is an angle grinder with a thin cutting wheel. Walther makes an excellent one called "zipcut". Then you can pound out the remnants with a punch and hammer. That bolt is way too much for your average Sawzall blade. I have some Lennox "Torch" blades and they will cut hardened steel if used slow and with lubricant. By torch I assume you mean propane? If you had oxy acetylene it would have taken 5 minutes. It will be easier to reinstall!
