The first time doing any job is usually a learning experience as simple as it might seem. Well the first thing I learned is that the grease gun is not like a caulking gun. The plunger needs to be pushed all the way in. Mine would not go in and back to you tube for the answer which was to wiggle it a little with the cylinder unscrewed a bit. Next, the LocknLube came with a great tip which locked on the zerk allowing up to 10,000 psi of force. Unfortunately, I could only reach one zerk because the tip was so long the tires were in the way of the rest. Since I was doing this at the storage lot not close to any autoparts store I proceeded to remove the wheels and finish the job. When I got home I ordered a 90 degree tip from Amazon. The suspension creaking that alerted me to the problem was solved.
