Review on LUBE LOCKER LLR-D030 Lubelocker: Superior Sealing Solution for Optimal Lubrication by Mark Turner

Not yet removed or used. My jeep's front diff doesn't have a drain so the cover has to be removed for every grease change. In the past it was very difficult to remove the entire RTV to make sure it didn't leak. This time I took extra care to ensure the surfaces were 100% clean and dry. The fit was perfect and nothing leaked. It remains to be seen how well the pad will perform when reused. So far, so good.
