I will admit...I don't know hardly anything about my Caliber except how to drive it..put gas in it and put air in my tires.

I just took my car into have a simple oil change and the vehicle inspection has 4 things under "additional recommended services".

They are: 1.Front Right axle leaking grease. 2.Trans-axle shaft seal leaking(Right). 3.Rear pads 3mm. 4.Both outer rods (tie or tire) rods bad.

Just wanting to know how urgent/how soon I should get my car back into the shop to get these things fixed. I don't want to wait too long to get them fixed.

 

It depends on How bad it is. Maybe you should go to another Reputable shop and ask for a Free 2nd opinion. Inspect the Lower Ball Joint too, sometimes they get mistaken from Tie rod end play.
3mm brake pad, you should be able to stretch another Oil Change. Tie rod end, depends on how loose it is, and how new is your tire. Because Bad tie rod end can throw off alignment and chew up your tires.

As for the Axle shaft leak, is it dripping on the floor bad? or just a little sippage.
Check Trans fluid level (requires special tool, dealership and many shops would have them). If it is little bit of wet spot, and trans fluid lvl checks out OK, you could stretch it maybe another oil change or 2. maybe even longer.
remember, your car is Green CVT fluid Only for the Transmission, DO NOT put in regular red ATF.

If you plan on keeping the car, These are general wear and tear item. I recommed you to fix it ASAP.
