Hi Andy,

The 69516497 unfortunately didn't come back to anything for me, but I can say that the manufacturer doesn't really offer replacement cylinders so you would either need to replace the jack entirely or reach out to a local company that works on hydraulic cylinders to see if they can rebuild it for you. If you want to go the replacement route then we have a few options to choose through. If you're wanting to stick with the Bulldog brand you can swap to the # BD182701.

If you're wanting something with a motor to make lifting and lowering the trailer faster and easier then you could go with the etrailer # e33VV you were looking at. This would come with a wired remote to plug in and activate the motor. This jack has a 12,000lb lift capacity and 15,000lb support capacity so it's likely just a bit higher rated than your current jack.

Hey Andy, did you end up replacing your Bulldog jack or having the cylinder rebuilt locally? Knowing what worked for you could help others dealing with a similar leak.
