Replace your worn or broken clutch release bearing collar with a New OEM Genuine Toyota part. This collar is used in all 1981-1988 Pickup's and 1984-1989 4Runner's that utilize a 2-piece release bearing design. When replacing your clutch, inspect the release collar for damage and replace if there is excessive ware. A worn out release bearing collar will shorten the life of the release bearing and pressure plate, and cause chatter resulting in  increased wear to the transmission nose cone. We highly recommend this Genuine Toyota part to ensure proper clutch operation for many miles to come. Always lubricate the contact points, as prescribed in your Toyota repair manual, to prevent premature wear.
