Rear Frame to Body Isolator

[dshawk]

I need to replace the Body-to-frame mounting bushing—specifically a rear frame-to-body isolator in my 2000/2001 E350 Super Duty Chinook. The part is not used by the OEM, nor does the company have the ability to access records to pre 2018 vehicles. I am hopeful someone in this forum has a solution!!!

These are MORryde rubber springs, available at Amazon at a low price: https://www.amazon.com/gp/product/B073Q ... HGJUF&th=1 Search MORryde in the forum and there have been several threads.

This is my post from 3 years ago when I had my MorRyde springs shear in half like yours on my trip west. The replacements they ordered for my 2000 Concourse fit perfect, $500 for the 2 springs, MORryde Part# 94-6313.

If I hadn't been on my trip west and stuck, and the local spring shops hadn't had a minimum 5-6 weeks wait on getting any at the time (2022 sucked), I would have removed them and gotten new progressive spring packs instead. I believe it is a better ride, and rocks less in broadside winds (I took a test drive in a Concourse with them when visiting Weltec).

Note the part above does NOT include the metal brackets that actually attach to the frame and spring pack. Mine were rusted but still strong - yours do look a bit worse than mine, so someone will need to decide how strong they still are. If you need to replace them, then I'd really, really, go with a large progressive spring pack and new brackets instead. Weldtec in San Diego looked at mine (after I'd already been forced to get the new MorRyde just a month earlier) and said it'd probably take them a few hours to get the brackets off, so if they have to go, anyway...

And if you do go with the new progessive spring pack, I'd also get new shocks - Fox 2.0 Tuned. They are progressive shocks, so they react different for small bumps like over gravel vs large bumps like pavement cracks or potholes. Certainly my test ride with the Concourse at WeldTec felt great, even bouncing over speed bumps at 10-15 mph (could never do that with the new MorRyde I have).

I was planning on doing all that as soon as I got west to San Diego, then had the stupid MorRyde shear in half on the trip and cost $1700 to replace (stupid RV shop cost much more than other people have paid using truck shops) - my usual luck.
