Can you tell me how many motor mounts are in the front? Been looking all over can’t get any info. I know my motor rises when in the front when I tested for motor mount are there 2 in the front and is it hard to change? Thanks. Hope everyone is doing well during lock down.

There are three mounts total. One on the engine and two on the trans-axle. The engine mount is easy to replace, you get the vehicle in the air, then use a wrench to remove the nuts from the top studs on the mount, then remove the bottom ones. Next use a jack or an engine hoist to lift the engine just enough to get the mount out, reverse the process to install the new one. The nuts are torqued to 22 ft lbs for all 4. The book tells you to remove a bracket and brace, but that only applies to the OEM mount replacement. Most of the available ones are just the rubberized solid mount.
The two trans-axle mounts are almost the same process except the steering rack is in the way on the rear mount so you need to loosen the bolts for it and move it some while moving the mount. On both it is sometimes easier to remove the mounting bracket from the transmission with the mount, then replace the mount and put the brackets back on as a unit. Depends on the tools you have and condition of the mounts. The front mounts usually come with the bracket as part of the mount as well.

Shouldn't need to but if you wanted extra room you could. Usually you just move the bracket under the A/C.

Did you have any luck or no time to wrestle with it yet? No rush, just checking.
