A-Arm Bearings: The Independent suspension on an ATV has four (4) crucial mounting points on each side, both front/rear and top/bottom, where each of these ends has roller/needle bearings. An ATV with independent rear suspension or IRS also has bearings there. It is possible that there is a poly bushing instead of bearing since ATV models vary but more often than not, there are needle bearings inside. The crucial mounting spots will sometimes have grease fitting for lubricating the bearings. If an ATV has none, grease fitting can simply be added with minimal mess. Spinning bearings greatly help the ATV’s suspension to travel freely. Be sure to attend to the bearings after months of demanding off-roading.
Seals: There are various types of seals on most ATV applications ranging from o-ring to low-drag double-lipped seals. Each bearing is distinctive and the necessities for further resistance vary, but there will usually be more double-lip seals that have metal re-enforcement in them on all ATVs. The seal is a means for additional protection and can be torn, pricked and penetrated through high-pressure washing. Seals call for replacement with the bearings it protects to keep both working impeccably.
