Leaf spring bushings too small?


Recommended Posts

So I ordered new bushing for my leaf springs and came across an odd issue. The front bushings fit in the spring eyelets just fine and are pressed in nice and snug. The rear bushings, for some reason, are sloppy and don't seem to fit my 78' 620 King Cab's eyelets in the spring or the frame. It's the same with another set of leaf springs that I pulled off of a buddy's truck. Did I end up with the wrong ones or am I going to have to make sleeves for these?IMG_5570.thumb.jpeg.e39a5495e8820520b3479e49b5b639ef.jpegIMG_5571.thumb.jpeg.e6423e6dc4bdfc8121201a661a247c46.jpeg

@datzenmikethat's what I'm guessing, but the options I have to choose from to order all point to this part number. I think I've heard that the 78-79 bushings are different but every website lists the same bushings across all model years. Wondering if 720 or d21 bushings might work if I can also find matching shackles

Front rubber bushing is 55045-B5000 for all years. 720 and D21s use a two part front bushing.

Rear rubber bushings are 55045-B0700

 

These part numbers are only for the 620 and do not list for any other vehicle.

I am pretty sure the manufacturer are assuming they are the same for all models... I remember running into this with my 521... 

Try looking at energy suspension for universal fit... and look it up by size...

By the number i think it says on your caliper it looks like 1.325/1.330..

I found jeep ones at 1.330...

You'd only be using half the kit....

not sure the bolt size if these would work...

Also the universal ones from energy suspension...

These are 1.325 od....

Same deal witht the bolt... might need to get sleeve to adapt the inner size to the bolt...

Goodluck...

Thanks for the help! I'll look into the jeep bushings. I think also I saw someone say that the 720 rear bushings are the same size as the 78/79 rears. I'll probably just go with the jeep stuff to be safe
