I installed mine a few weeks back. No trouble at all. I see that your thru bolt isn't showing a lot of left over thread. See mine for reference. There is at least 5-6 threads on the thru bolt when completely tighten down.

I was going to say, contact Tim at Brown Dog. Good guy. Helpful. Knows his stuff.

The BD mounting instructions don’t have torque specs if I recall correctly. The washer needs to be loose against the mount to avoid vibes. The nut should not come loose since it’s a lock fitting, or something like that. There’s a particular way to tighten it. Call Tim at BD
Hope you get it worked out. It can be a pain. I got DW the day I installed mine. Took 3 months to sort that out.
No torque specs were provided with the BD kit. Instructions were "nice and tight" on the bolts. I torqued mine down to FSM values. May be different for the 4 cylinders.
• Thru-Bolts = 48 ft. lb.
• Bracket Bolts = 40 ft. lb.
• Bracket Stud Nuts = 30 ft. lb.
I bought the M.O.R.E. Bombproof mounts and they clearly state in the instructions and sales promotions that they will cause additional vibrations in the 2.5. I guess they were right. The Brown Dog are almost the same mount as the M.O.R.E.'s only painted yellow instead of being plated. Hope you find a solution.

That is what my TJ had on it when I purchased it, and it was the first thing I took off and replace with the stock rubber mounts (as well as the transmission replacing the poly transmission mount). In my case there was no reason for those mounts. Although I do think that those mounts helped me negotiate 2 grand off the asking price since the jeep vibrated so bad most folks that test drove it probably thought there was something seriously wrong with it so it sat on their lot for 4 months.
OP
I was expected some vibrations, not ones that would rattle my glove box and radio.
Debating on going back, I'll call brown dog first. Just wanted to get ride of my transfer case drop.
You can also use the OEM rubber mounts along with the one-inch block.

Update:
Just got off the phone with Tim at brown dog! He said the issue I was having was common with the 2.5, and instead of prying to get it lined up, or what I was mainly using a rachet strap to ac bracket to front bumper, instead to ratchet straps on rear driveline and connect to frame on under the passenger side. Tim said this will and in rotating to motor to the mount insead of pulling it into position.
Also, he said with the 2.5 mounts the tightening of the through bolts isn't much of an issue since the bushings are different. The 2.5 bushings use a through pin design instead of washers.
Going to give this a shot!!!

I bet Tim at BD would honor the return if you can't get rid of the excessive vibes. I agree with whoever said Phone Call. Email is one thing but he's going to want all kinds of information. He did when I called him. Year, engine, details of vibes, etc...
EDIT: Looks like you've already got some direction, Disregard!
