Help Repair Busted Rear Leaf Suspension W350 Dually

Help Repair Busted Read Leaf Suspension W350 Dually

Hi yall,

I have a 1993 Dodge Diesel W350 5-Seed Flatbed Dually... with a little, issue. The main leaf on the rear left is snapped, and although the car looks like it can run just fine, obviously I cannot drive it in this condition. I am curious on what I would need to have ready to replace, when doing this sort of repair. I probably will not do it myself because I don't have a garage or an area to work. But the questions are:

1) are the bolts going to be really hard to get out? What are all the things to replace OTHER than the leaf... because I know things will probably fall apart the second we start unbolting things.
2) I think its obvious that if I replace one side, I should just do both. In that case, is there something else I also should replace while the rear is apart.
3) anyone know of any LOS ANGELES , CA repair places that would know how to do this and it wouldn't cost an arm and leg.

I think I forgot a million other questions but I think its pretty clear that I first need to repair this broken piece. Please, any help would greatly be appreciated.

-Manny

The most affordable way to conquer these ugly jobs is DIY.

Hangers and shackles are probably rusted through in various places. I'd be prepared to sever them at the frame rivets and start over. Clean some of the rusty scale off the frame at the same time, paint as you wish. If you don't like the rear end, its a good time to change it.

Check my thread for inspiration....

Not sure how that spring bent like that before snapping!!

I would start soaking everything in PB blaster ASAP, every bolt, nut line and clip you can see that may need to be unhooked or removed. That LH side front eye bolt is a PITA since it runs in behind the fuel tank....so depending on how things come apart you may also have to drop the fuel tank.

Looks like your front and rear spring hangers on the frame are in decent shape, so doubt you will have to replace those. But as you mentioned replace both rear spring packs at the same time.

That looks like an axle wrap break, watch the burn outs! Other side may look the same. Btdt.

exactly what I was thinking.. looks the same as my drivers side leaf I broke drag racing a mustang (of course this occurred on a closed course with profesional drivers and not on a public street )

I know how heavy myself and others load our first gens. I bet the frame was resting on the lift block when it failed. Bumpstops tend to disappear over the years.

If you only want to deal with one side, try to find another DW250/350 main leaf with the 3/4" eye bolts.... and get it in there. Its still a lot of ugly work though. Best to take a full assessment of the rear suspension and axle before you dig in.

Mine looked the same... until I chipped the packed dirt and scale out from the top of them. Then they looked like swiss cheese. And the frame had some thinning too.

This is why it is a good idea to clean that area occasionally and if you live in the rust belt drill a drain hole so salt water doesn’t puddle. My truck is from the desert and the mounts look almost brand new!!!!

Absolutely! ...trouble is, its tough to undo 20+ years of neglect.

Thank you. I did find a d250 and took its left leaf set. However, I just noticed the bolt is much smaller as is the bushing... and from what I've read/seen, the bushing cannot really be swapped... unless theres some magic... so, do I order all three bushings (and possibly bolts if Mine need to be cut?) Thanks. I think you are right that they are 3/4". They seem LARGE...

Dually will have the 3/4 inch bolt. Don't think there's a bushing to convert, find a spring shop and have them fix it.

My D250's (std cabs) have 5/8" bolts. My D300, W300, and '93 W250 club used 3/4" bolts. The leaf packs with the larger bolts are flatter and have more leafs. I don't know if the bushing swaps... changing bushing really gets away from a quick-fix.

A whole new jobber leaf pack (or a good used one) is probably cheaper than having a spring shop repair anything. The driver side is the heavy side of the truck anyways... couldn't hurt to have a fresh/better spring on the one side.
