Part #:
The reason I decided on getting this motor mount lift over the other ones was the quality involved. I had seen the other ones and wasn't to confident with their strength. These come with a welded web inside, and rubber bushing that is similar to factory standards. I won't say it is like the factory bushing, since it doesn't look anything like it, but it is really quiet and doesn't transmit the vibrations like the poly bushing do. The bushing actually looks like the same ones that are used in the control arms.

The Motor Mounts that I had came off my '99 TJ. Now they were almost brand new, I had only bought them in August 2002. I was starting another round of modifications and had installed these in preparation to do a new NV4500/Atlas II when I was told that I could buy a Rubicon instead. Okay twist my arm. I had been reading the boards seeing that lots of people were having problems installing these and that raised a little concern. I did have some rubbing on my '99, but that was an installation issue. I realized from the boards that the problem was centered on the passenger side. I had looked at how the vehicle was and made decisions on where to start. Being an engineer and working on ships and jet engines I am used to trying to figure out how to get things in and out of tight places. Here is what I did. Now M.O.R.E's instruction have you start on the drivers side.
First thing was to throw out the directions. Okay I did this before, so I pretty much know them. I started on the passenger side. I had noticed that this engine bracket had an oval hole for the attachment bolt. The factory mount was as far out as it could go in this hole. This is where I figure the problem was. I did this install by myself in 2 hours, which included looking for my 18mm socket, taking pictures, measuring and generally taking my time with it. I did follow the directions when it came to taking off the fan shroud. I put in a body lift at the same time so I didn't have to drill. The engine lifted fine with a jack under the oil pan. I dented the oil pan slightly when I lifted it, but that was my fault for not paying attention.

I ran this around, and hit the construction site down the road from me. No bangs, no contact, nothing, believe me I tried to get it to hit. Nice and quiet, it appears to have plenty of clearance all around. I suspect that the oval hole is the problem. Now I don't feel like turning around taking it all out just to follow the directions from M.O.R.E to prove this, call me lazy.
I have since done this lift a couple more times and found that you can remove both mounts, install the new ones and then lift the engine up to insert the mount to engine bolts. It was actually easier this way. Installation of the JKS Budget MML and Tri-County Gear MML follow the same basic outline, only difference is the MML pieces.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work. While I have spent many years working on mechanical systems, I am not an expert, nor do I pretend to be one. I hope these write ups have been useful to you.
