Weird Tokico HP sound!!!

[JoseProte83]

Well guys, have been riding on Tokico's for more than five years and this is the first time I have noticed this. I replaced my old Tokico's a few moths ago with new ones. I started noticing some weird sound during heavy compression. I decided to ride close to the road divisional wall and my ears did not deceived me. Every time I take a part of the road that is uneven, where the shocks needs to do full compression or close, I heard the sound of leaking air. I did not noticed this early cause I spend most of the times with the radio and windows up. I have never heard this sound with my old shocks and I used to drive a lot with the windows down, so I was wondering if this may be a factory problem (Seals, etcc inside shocks) or something. Any inputs? I forgot to mention, the car rides like normal, but a little weird under heavy maneuvering.

My Illuminas hiss as well and I didn't notice it on the old HPs I had installed. I've understood it to be normal, but it's also possibly due to bad seals (though I have it on both rears).

Check for leaking strut oil.
