Put an OEM rubber transmission mount in replacing the Energy Suspension poly. Need to drive it a bit and see if any effect on my squeak.

Daughter came over to craft shop with wife/mom so I got her car's oil changed and a wash then cleaned the inside windows.
Not sure if the squeak is gone, but holy crap, this thing rides like a different truck. Never again, unless racecar, will i do a poly transmission mount. Also gone is the weird harmonic vibration I would get at 70MPH/2100RPM in 4th.

=/ . I have a new Energy Suspension trans mount sitting on my work bench. BUT I ALSO just replaced the transmission mount with a parts store unit. I was hoping to see the same results like the Front/rear sway bar bushings did. Best mod under $100 bucks I've done.

Since you've already swapped it out before, you know the process. Would take you 15 minutes to put the ES one in and give it a couple months driving. You might like it? Mine was in for 5 years - only reason I got it was because I had a horrible drivetrain clunk that I was chasing with the parts cannon, which ended up being the slip yoke needed greasing.

Agreed - poly sway bar bushing and end links were an immediate improvement.

The lug nuts were super stuck on, tried everything from brute force and jumping on the wrench. Ended up rounding these two old bolts.

Bought one of these extractor/twist sockets, hammered it on and used a proper breaker bar with a pipe on it. Loud bang and it was off. Easy to remove the broken nut from the tool if you tighten them a little on the wheel again if they have enough grip on a normal 6 sided socket to be removed. Tought they were a gimmick, but these did the job first try on two nuts.

Off to buy new nuts for all four wheels now, they are swollen, rusty, they stick to the metal and need replacing (Probably won't swap until next time wheels come off)
