Your F-150 rear end axle is obviously a crucial component of your truck, and when it begins to grind, squeal, or make any other noises when you are turning or driving at high speeds, timely repairs are essential for your safety as well as prevention of damage to other parts of your truck. If your rear differential needs attention, adjustment or repair of various components of the axle assembly may be in order. Look for repair kits for Ford 8.8-inch axles with 31 splines. Some of these kits include side gears, washers, and pinion shafts. If you need ring and pinion gears to complete the job, look for kits that include these parts as well as pinion nuts, pinion and carrier bearings, pinion seals, ring gear bolts, cover gaskets, and crush sleeves. If you have determined that your spacer shims are the problem, the vast inventory on eBay is sure to have those necessary components, too. To completely replace your axle, look for a rear end axle assembly complete with rear disc brakes and ring gear. Regardless of whether a complete overhaul of your F-150 rear end assembly or some fine-tuning is in order, you can be sure to be well on your way to quiet, smooth driving in no time.Shop the large inventory of car and truck parts and other car and truck differentials and parts!
