After 18 years I had to replace my front jacks.. Motors still ok.
I have greased both of them both 2 times over the years.
One jack was clanking really bad... I knew that the guide at the bottom of the jack screw was broken off same as KKeller's. The other, the wafer bearing and washers were gone along with major rust on the inside tube.
I replaced both... Never have had a problem with the rears... I did tear them down about 8 years ago and did the clean and grease...They are the 4100's.
The new jacks I got are 2900lb capacity v/s2500. There is a drain hole at the bottom of the foot and the inside tube is not painted...It looks like galvanized steel. That seems like the only visible difference.
I have not seen any pictures nor info on the new HJ's shown in the previous posts... Quite interesting.
