If anyone has the latest generation of Chrysler minivan, you may well know of the chance that their powered liftgate chains fail.
A web search for solutions will only reveal that the chain can't be purchased separately from the power unit. The entire new power unit runs from $190-$400, depending on where you find one. No sense looking for a used one, as that chain will already be weakened just from normal use.
I'm cheap and mechanically "obsessed", so I did some research. I only saw the number '25' on the side of the chain links. Not having a lot of chain wisdom, I googled "#25 chain". Turns out, that is a kid's electric scooter chain.
Found a place online, ElectricSccoterParts.com , bought 12" of chain, a couple of master links, a 1/2 link, and a 1 & 1/2 link (just in case). Shipped quickly.
Pulled out the dremel and cut the pin ends off some links. Removed the bad section of chain (several links had been broken). Installed the new section of chain using the master links and I think I also used the 1/2 link.
All this cost less than $19!
Now the lifgate works perfectly and my wife likes life again!
Dealer repair would have been a few hundred bucks, I guess.
My only regret is that the new chain section was beefier than the original Chrysler chain. So, I probably shoulda replaced the entire chain instead of splicing old with new.
