The Trim Master trim tabs are easily repaired if the actuator seals start to leak. Removing the end cap is greatly facilitated by using the OTC Adjustable Gland Nut Wrench #7463 available at any NAPA autoparts store. I did not put a 1/2" socket wrench on the Gland Nut Wrench, hand force was all that was needed to remove the end cap. The U-Seal came from a local hydraulic shop and they were a great help figuring out the proper seal needed. I heated up the U-Seal with a heat gun, lubed it up with oil and it was fairly easy to stretch on the actuator piston. I was quite happy to figure this out as Trim Master Company went out of business a few years ago and we owners of their trim tabs are now on our own.
