I was installing new shocks today, and on a break I decided to look at the rear frame on my recently purchased (1.5 months ago) '95 Pathy. I was recalling a thread that mentioned keeping your drain (weep) holes clear in the frame to avoid the rust, so I went to check on them. HOLY @#$%! Looking behind the rear wheels, I saw this fine silty sand plugging my drain holes. So I grabbed my garden hose, threw on a nozzle and blasted water into those holes until they ran clear. I then looked under the passenger seats and found more drain holes and blasted those too, and under the driver's and co-pilot's seats as well. Then I did the whole thing over again 2 more times. Honestly, I'm gonna sweep up the mud when it dries tomorrow and weigh it. I cannot believe how much crap was inside of my frame. Another part of my maintenance program is to now flush the frame in spring and fall. I urge all of you to do it. Even if they look clean, you can stick your little finger in the drain hole, and feel if there is dirt inside. Flushing your frame keeps your ride happy.
