I have a 2002 ext
The clicking from the front can be two things. 1.Is the cv joint as you are saying if it is front wheel drive witch it is not. 2. The most likely thing that you are hearing is a front wheel bearing. I would have the front wheel bearings checked and replaced if needed.

I have a 02 cadillac
Only the rear ones should have the air lift feature, although there is a conversion kit that may have been used to add air lift to the front.
The type of shocks you have (front and back) will depend on whether you have the Electronic Suspension system option. Without this, the shocks are pretty standard. However, if you have this, they are all (front and back) controlled electronically to adjust the firmness of the shocks to assist in keeping the vehicle level during maneuvers. You can quickly tell if you have this option by examining one of the shocks to see if there is an electrical connection on the side. If you have this system, these can be very expensive and hard to find, and GM has had a lot of trouble with them. As a result, many owners have replaced them with standard aftermarket struts (which includes air lift versions for the back). However, the old shock electrical cables have to be specially terminated if you do this (see The Cadillac User Forum for more info).

Memory seats adjust on there own as well as mirrors
BCM has nothing to do with this function , MMM - memory mirror module !
Memory Mirror System Operation
The MMM is capable of storing mirror position for 2 different drivers. Mirror position is determined by both horizontal and vertical position sensors in each of the power mirrors. The MMM supplies a reference voltage and a low reference to these sensors and determines mirror position through the horizontal and vertical position signal circuits.
The MMM receives power through the battery supply voltage circuit and the MIR/LOCK fuse and a constant ground source. Any time that battery voltage is disconnected and then connected from the MMM, the MMM will enter the mirror relearn mode. The mirror relearn mode can also be commanded using a scan tool. Refer to Memory Mirror Module Learn for further information.The memory switch receives power through the battery supply voltage circuit and the MIR/LOCK fuse. The MMM upon receipt of a memory switch signal input, a class 2 message from the SIC or a class 2 message from the PCM indicating that the transmission is in park, will then supply battery voltage and ground to the appropriate power mirror motors through the mirror motor control circuits to move the mirrors to the predetermined positions.
DTC B1586, B1596, B1616, or B1626
The mirror horizontal and vertical position sensors are potentiometers. The Memory Mirror Module (MMM) provides these sensors with a 5 volt reference circuit and a low reference circuit. The MMM monitors the horizontal and vertical position sensor signal circuits which change values based on mirror position. These voltage values are used to determine mirror position and can be set into memory. When the MMM receives a memory recall request, the MMM will control the power mirror to the memory position based on the horizontal and vertical position sensor signal values.
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, observe the mirror horizontal and vertical position parameters in the Memory Mirror Module (MMM) data list.
Operate both the left and right mirrors through the full range of movements.
Does the scan tool indicate that the left and right mirror horizontal and vertical position parameters are within the specified range?
Memory Seat System Components
The memory seat system consists of the following components:
• Power seat switch assembly
• Memory recall switch assembly
• Horizontal adjuster motor
• Front vertical adjuster motor
• Rear vertical adjuster motor
• Recline adjuster motor
• Memory seat module
• Memory mirror module
• SEAT 25A circuit breaker
• MIR/LOCK 3A fuse
Your best bet , take it to a qualified repair shop !

2002 Cadillac Escalade 4x4 When
If you think the dealer caused it get a hold of GM district rep .Talk to the service manager . If the dealer Technician's can't fix it , get the factory involved . In most cases if it is something they did they need to take care of it ,free .
