Cab ride shock absorbers

[Wingnut13]

After my last ride I did a walk around as per standard. I heard an air leak from the passenger side cab air ride can. Today I decided to look into the issue and found the leak was from the top shock retention pin O-Ring. Once I had the unit it out it sounded faintly like a clunky hourglass, and once I had the unit apart I found the top shock bushing had deteriorated into rubber dust. I'm looking for a suitable substitute for the bushing and O-Rings. The shock eye ID is .875 (7/8") and the OD of the pin is .625 (5/8"). If I can locate a bushing and the correct O-Ring I'll post it up.

Id suggest make your own with pourable polyurethane

Try energy suspension’s website they list poly bushings by sizes if I recall

I did check out the energy suspension website for universal fir bushings, nothing too close there. Making a bushing may be the way to go, either poured or machined. Anyone have a tip for what to replace the metal band with that holds the airbag to the body?

so far that is what no one has tried yet. Last I heard there were only one or two companies in all of US that do that type of banning.

Yea, mine are not leaking yet, but I am planning on aftermarket cab shocks and airbags to replace these aging one piece units…

Well, I made progress, and found out I hosed myself. I didn't get the message about not cutting that top band that holds the sleeve on. I just ran across that thread today. The job would have been done had I not done that. So I'm trying to crack that nut now.

As far as the O-rings go that seal the top pin, I have a few O-ring kits but the one from Harbor Freight had the right size. Cost $7 for that kit as I recall.

So for as the bushings go I had some derlin round stock and had new bushings in no time. I just used some Loktite red to hold the new bushing in the eye of the shock.

To hopefully close this thread out I ended up using a regular hose clamp and once clamped down with a bit more help I used my TIG to tack weld the band closed. I put the unit on the truck and have taken a few rides, half expecting the band to pop, it hasn't. The ride is so much nicer with that bushing replaced. That metal on metal hammering is now gone.

Keep us posted on short and long term success of the band holding her good. Did you add any sealant to the end of the sleeve prior to install?

This is what I have been using, a piece of MB coolant hose off an Unimog. It fits perfectly. Other locally available hoses should fit too. The fit is snug so silicon grease helps.

LOL..... like they say.. if it works... it works
