Seems like a good one to look up in the official shop manual if you are going to DIY. I am sure they have the details there.

Thanks for the video instructions. Learned a few things!
What are the symptoms of failed transmission and engine mounts?

I don't have a problem with replacing them at a certain mileage either if needed? Any suggestions?
I have had a few launches with some wheel hop and I know that's bad for the suspension. I back off immediately when it happens.

I have a tune and pulley so I am sure the extra power will accelerate the wear. Still feels as smooth as always right now though.

  • Increased Vibrations. One of the most common engine mount symptoms is increased vibrations while using your vehicle. ...
  • Rocky Start. ...
  • A Bumpier Ride. ...
  • Impact Noises. ...
  • Visual Wear.
  • slamming into gears especially during cold starts when rpms are higher
  • low transmission fluid bad solenoids can also have the same symptoms
overall the transmission shifts and engine will feel clunky VS solid, smooth

There are two engine mounts, one on each side of the engine attached to the subframe.





To replace them requires supporting the engine from the top.

There is also a transfer case mount #2 and a vibration damper #14
Transfer case fluid# 18 $155.00 per liter! I thought the differential fluid was expensive

The problem is getting the power steering rack out of the way even if I remove the bolts the lines going to it from the engine are too tight

I removed all engine mount bolts
I tried to jack up the engine from the oil pan and the whole car was getting lifted not just the engine
I only did 3-4 pump on the jack before bringing it back down did not want to break anything
I think something else is holding the engine to the frame

Looks like the power steering lines have to be removed

  • Be prepared to collect escaping fluids.
  • Before disconnecting or removing components, ensure the area around the joint faces and connections are clean. Plug open connections to prevent contamination.
  • Cap the power steering line to prevent loses of fluid and dirt ingress.
  • If power steering fluid is spilt on the paintwork, the effected area must be immediately washed down with cold water. Failure to follow this instruction may result in damage to the vehicle.
  • Install new o-ring seals
  1. Renew Part: Power steering hose O-ring seal(s) Quantity: 1.
    Torque: 25 Nm
