Repair-It

I can't tell if the motor mounts may be the source of my funky driveline vibration (not 95% resolved like I thought earlier - test drove more and while slightly diminished, it's still mostly there).

The driver's mount thin-bottom rubber was cracked and tore off really easily. I wonder if it was fluid-filled a really long time ago. The passenger mount visually appears to be a little newer. I need to get someone to get in the Jeep and do drive/reverse pulls on the lift so I can see what's moving around.

I should probably drive it at some point. I probably have an opinion on this.

Finally got Max to help me load the engine and watch the mounts - holy mount movement on the drivers side batman.

This appears to be the somewhat-cheapest Mopar mounts I've seen:

Looks like they'd be about $210 for the pair shipped.

At least these guys are in IN:

$20 shipping though, so about $225.

These guys claim to have nationwide warehouses. Was based in a "real" Jeep dealer in MO, so figured I'd give them a shot.

Order placed.

Just realized I could've tried looking up by PN on the RockAuto website. They don't have the latest Jeep PN listed, but they do have an interchangeable old one. I think I'd rather get "fresh" Jeep stock, so probably better off with the order I have. It's only like $10 cheaper at RockAuto anyhow.

Changed plugs last night. Uneventful. Might have been original plugs based on patina...

Also did initial dump and refill of transmission. About 4 qts came out. Drain plug was PITA and I had to mangle it to get it out with a hammer/chisel - replacement pan came with a new one already installed.

Drove a few miles this morning and I'm planning to drop pan/filter and replace today.

Any difference with 16 new plugs?

No notable difference in driveability or smoothness - may be more noticeable/might have made more of a difference if the engine were somewhat-motion restrained in the engine bay.

Managed to get the pan/filter swapped today among meetings.

I think someone may have put new rotors on at least the front, but didn't change the pads. I think these are pretty much end-of-life.
