The grease coming from the brass vent is normal, GM has a bulletin on it. These struts are inverted insert dampers, the grease is not a sign that they are "blown". I have had the Z/28 DSSV's apart and they will leak grease also. They are designed very similar to the ZLE DSSVs. The excessive grease will eventually stop coming from the breather. Judging from what I saw from my DSSVs, there is plenty of grease to do the job.
I installed a set of Z/28 DSSVs on my '14 1LE. The DSSVs were brand new and at some point after use I had some grease coming out of the sintered brass vent. IIRC, I noticed this when I removed them to install lowering spring. In doing that I disassembled the front DSSVs. Primary reason in doing this was I wanted to see the bumpstop, which is inside the assembly. The fronts come apart easy. Once apart I could see how the insert works within the body. Upon reassembly, I removed the brass vent, cleaned it with BraKleen and reinstalled. I broke one of the brass vents on reassembly, but I found the same ones somewhere on the interwebs. If anyone ever breaks one of those vents, I have extra, just hit me up with a PM.
Once I cleaned the brass vent, I have not had any excess grease coming out. That has been since 2016 and I track my car heavily. No grease leaking and no problems with the DSSVs. |
Thanks for this. Now that I recall, yes I did have the thick yellowish grease out of the brass vent first. I wiped this away and never really saw it again. The fluid that was covering the bottom of the strut, suspension and the inside of the wheel hub was an oil and this seemed to be coming out the bottom nut. However that could be just where it collected due to gravity. The struts definitely needed replacing in my situation.
