I heard they were tricky to install and are easily screwed up. I've gotten some advice but has anyone here had to do this and run into unusual problems?

97 4x4 HO...

 

I just put some Rusty's mounts in a 97' Cherokee...the factory rubber ones had 140k and were trash. It was very straight forward actually. I read a lot of people had issues with the driver side mount (ie- spacers didn't fit right) and also said you had to take off the oil filter to get the bolt through...those must have been pre-97' style because mine both went in perfectly.

Whole job took about an hour...no problems whatsoever

 

Mine on my 98 were a piece of cake. Took about an hour as well, I did remove the airbox for the drivers side which helped alot.

 

3xs on my 96

 

not a hard job really, just gotta be careful

i lifted up on the oil pan with a jack with some wood on the top of it.
i DID have to trim the driver side mount that was on the engine, 5-10 mins with a angle grinder and some 60 grit pads and it was all good.

using ironman4x4fab mounts here, was amazed when i first started it and the engine wasnt rocking back and forth at all haha

 

Yea, I forgot to mention I took off the air box, and jacked the engine up with a floor jack and some plywood under the oil pan.

Night and day difference....if I had to do it again, I probably wouldn't use Poly mounts. They are a bit stiff for a daily driver IMO
