The photos are back in the OP, I will see if I can link them where they show up without having to click on each one. Imgur has several options. Will see if I can make an improvement. Sold the Subaru many years ago. I have no idea if they have changed the manufacture of the struts....it not, the problem likely remains. By now future owners should be able to advise if this sticking rear strut is still an issue. It's pretty simple what is causing the problem. Mine kept doing this every 10K miles or so and the dealer kept putting in new struts. One day I decided to take them apart and see what the problem was. In inspection showed exactly what was causing this...waxy grease that was stuck to the outer wall of the strut and not being distributed by up and down movement of the inner piston. Secondly, there is no way to really pack the inner tube with grease, hence the grease alemite. These are common grease fittings installed on thousands of tools from weed eaters, riding mowers, motorcycles, autos, tractors, bushhogs, etc. They come in different sizes, different size and length threads, angle head, straight head....whatever is necessary for easy access when greasing time is necessary. They are not expensive and can be purchased at any auto supply store, Tractor Supply, etc.

The steel on the side of the strut is plenty strong for securing the fittings nor do they need to be tightened all the way down. The thread length varies so chose one what has a short threaded tail. The thread is tapered and tightens as the fitting is installed. Now to see if I can determine a better method for adding the original photos so each doesn't have t be clicked on. Hwy61

When I originally did this thread it was necessary for me to remove the struts and disassemble them, with all that entailed, in order to determine what corrective action if any could be made. The solution is easy....add a method for adding grease to the strut chamber. If someone were to figure out a way to drill though the outer housing and thread the steel there for a grease fitting without getting any shavings inside the housing.....the entire process could be accomplished in 20 min with only removal of the rear tires. Simply drill, tap and install the fitting....add grease. Reinstall tires and lower the car. You would want to make sure that your drill did not over penetrate and hit the inner assembly. Drill through the outer housing only....there are stops that can fastened to a drill bit to control depth.

I expect someone who understands what I'm suggesting could attempt this on any old struts to see if it could be done. I doubt the drill bit would get much debris inside the strut, not sure about threading the hole. Whatever steel shavings managed to get inside the housing would be caught in the nearby grease....would that migrate to an area where it could cause wear??? Could you take a Q Tip and carefully clean the hole before screwing in the grease fitting? If so, that would make this a very quick process. Just install a fitting in the location as shown below.

BTW, is this still an issue with later production cars. Mine was a 2005 STI which has since been sold.

The grease fitting location as shown above is midway between the upper and lower seals as I recall. Hwy61
