2016 Yukon XL repairs for 100k miles

Hello all! Here is an update because some of you asked and I need more advice. LOL. I went to the 2nd, locally owned place. Here's what they said:

- Coolant hose at bottom of tank is leaking and hose is soft; recommend immediate replacement.
- Rear air shocks are damaged and compressor is disconnected from them (Note: my vehicle was rear ended while parked a month after we bought it in 2016. There was $20k worth of work done to it and I wonder if this was never properly fixed during those repairs).
- Also saying front struts are leaking (again I don't notice anything with the ride; my dad says they're trying to make $$$ off me).
- Rear axle has oil seeping
- No signs of water pump leak

Re: shocks and struts: the guy suggested we consider a delete kit where we remove the air ride system and put in "standard" shocks and struts. Has anyone done this and how did it go? He is saying it's a much more cost effective move and will save us more money in the future. Thoughts on a delete kit?

Right now I'm leaning toward having them fix the coolant hose and dealing with the disconnected compressor. How important are the other leaks? Nothing drips onto the driveway at this time.

Finally - I do not have plans to replace this vehicle any time soon. I love it and try to take care of it. We have 4 kids at home and need a large vehicle. No interest in spending upwards of $100k to replace it and my husband is going to be upgrading his own truck soon so we need to spend $ on that, because we pay cash for our vehicles.

Thanks for your help!

4 kids. Why would a guy want you to add resistors made for home lighting projects to fool your stability system into thinking a potential rollover isn’t really happening so it can avoid it? That kit he’s referring to lowers resale and potentially makes it unable to sell or trade to a dealer. Why would they want to accept liability of a bypassed safety system?

Surge tank leak
- Oil pan leak
- Oil lines leaking
- Rear differential leak
- Water pump leak
- Brake fluid change
- Transmission service

Do the water pump & trans service ASAP. Also replace the carbon canister that’s know to pollute your entire fuel system when it fails ($125). Some labor & maint jobs on these 4WD / AWD trucks shakes hands.

The trans is removed for the 100k major service. It’s a $6-$8k part to replace if not maintained. Do the service! When the trans is out:

* the oil pan job goes from $4h to $1h.
* motor mounts from $9h to $4h.
* o ring on oil pump from $5h to $50 with doing the oil pan.
* front diff mounts from $5h to $2h
* Rear main seal $9h to $1h

Same goes for whatever oil lines are being referred to. Do *stuff ASAP during 100k major trans service. Missing it means those higher labor & repair items eat you alive. Properly addressed means another 100k trouble free miles.
