Looking for grease fittings

I have 2003 LT 1500 2WD 5.3L eith about 10K miles on it.

I'm hearing a periodic squeal from the left side, hard to tell if it's front or rear. I decided to see if a bit of grease would help, but I can't find any fittings where I expect them. Can anyone lend me a clue?

GM has decided to use sealed joints on the front ends now.
If you don't see any fittings in the usual locations, you have sealed joints and are NOT losing your mind :iceslolan

Great!

So, to deal with the squeal I should go to the dealer?!?

Not happy!

Thanks for your reply. I do appreciate it.

Don't deal with the squeal....Damn a GM tech that can rhyme :iceslolan

Look, your truck is under the 3/36 factory bumper to bumper warranty. Take it to the dealer and have them look at it...ain't going to cost you a dime.
Most dealers (or at least the ones I have worked at) have courtesy transportation and rentals (that are covered under warranty...no cost to you) available for you to use while your vehicle is in the shop.
GM wants you to be happy with your purchase and I have seen them go to some pretty wild extremes to bend over backwards to make the customer happy....you are not going to hear a lot of people (especially on the internet) tell you how well they were treated by GM and their dealer.
