The welded lift blocks may compress due to over tightening of the u-bolts or excess vehicle payloads, reducing the clamping force of the u-bolts. This could result in shifting and damage to the rear axle and drive shaft. Truxx will replace the affected lift blocks with non-welded aluminum or cast iron blocks to correct this concern. This recall is scheduled to begin on April 16, 2008. The Truxxx recall number is 08-01BLK.
