BAD BOLT's EXTENDER is great. SO MUCH BETTER THAN ANY OTHER. IT IS AT THE BOTTOM OF THIS THREAD CLICK HERE HWH front leveling jack spring installation...Ughhh!
My springs hook to foot. Retracted can pry off. STRETCHING new spring I obtained free about 40 Home Depot paint sticks. Cut to 2.5 inches. Used vise and bent spring to open up placed wood in... then bent other way. That stretched the spring. Did top and bottom. IT WORKED
My jack rod was extended when the spring and foot came off. Now it will not retract. I used a 2.5 ton air bottle jack. Raised the coach. Placed metal jack entender foot on wood block. Lowered jack. INSIDE pressed raise jack. ROD went up a little. AND over and over until rod was all the way up for spring install.
ACCORDING TO THIS
If a jack is slow to retract, before storing the jacks, spray a liberal amount of WD-40 on the jack rod(s) and store the jacks as you normally would. Excess WD-40 should be removed from the jack or jack foot after storing the jacks. Cleaning the jack rod as explained above should be done. Using WD-40 to assist in the retracting of jacks will probably not be a permanent fix. Anytime a jack needs assistance when retracting, some type of repair of the jack such as new springs or replacement of the jack will be needed to make a permanent repair.
