LIke any used car you buy the Summit need a little maintenance. Looked like the pillow block & axle shaft seals were worn out. The seals keep moisture & dirt out of the pillow blocks & axle slides. Replacing the is pretty straight forward. Remove the wheel & hex, remove the pillow block retainers, remove the pillow block balls. Now you can pull the pillow block off the axle. The axle seal is glued to each side of the slider. The seals will be replaced so you can just pull the axle out and let the seal tear. Clean the old seal off and clean the two halves of the old seal. Now slide the new seal down the end with the splines showing. Pull the seal up over the lip, when it’s seated drip a small amount of CA around where the seal meats the shaft. Wipe off excess. Give it a minute or 2 to cure. Slide the axles back together when they are almost together work the end of the seal up over the axle lip. Make sure it’s seated all the way around. Glue as above. Pop the clips off that hold the pillow seals on the blocks. The seal kit comes with seals and new retainers too. Place the seal over the hub, pop the retainer on. The bottom is the same. I use a dry lube for bike chains called Bike Medicine Purple Extreme, it goes on wet the dries so it doesn’t attract dirt and dust. Put the lube on the pillow block ball and the shaft. slide the ball through the seal. Screw the ball back into the A-arm being careful that the seal doesn’t twist, the lube will help with this. Do the same on the bottom. Put the hex back on and secure it and replace the wheel. Repeat on the other side. The progedure is the same for the rear.
