Oliver Travel Trailers Model Elite II. The axles used on this trailer are supplied by Dexter Axle. The axle model number is 6339056 is rated at 3,500 lbs. and is manufactured in Dexter's Georgia manufacturing facility. Oliver travel trailers was notified, by a customer, of a problem with one of these Dexter axles, whereby three of the nuts securing the hub and to the axle flange had come undone, this matter was rectified by a service appointment. Oliver travel Trailers became aware of a second issue with this Dexter axle model, this was raised by a different customer and consisted of replacing one of the nuts, this matter was rectified but raised a potential problem. Oliver Travel Trailers contacted Dexter to inquire in relation to the issues that arose. We determined that both axles were from the same batch manufactured by Dexter in January 2109. On checking our service records we identified another similar issue with one of the same model of axles that did not fall within that batch range. Oliver Travel Trailers reported that fact to Dexter and started an investigation into the matter. We determined that the torque range was between 45-70 ft. lbs. for the four bolts that secure the axle to the brake assembly. Oliver Travel Trailers began checking the torque range on the bolts and nuts in question on axles present on our, we found a number of bolts which were not tightened to the minimum torque setting, again this was conveyed to Dexter. the following day representatives of Dexter attended our Hohenwald facility and confirmed our findings relating to the torqueing of the nuts. Since then Dexter inform us that they have determined a time period for the scope of the defect which appears to be from the beginning of 2017 to the present day and this equates to 780 model 6339056 axles supplied to us. Dexter Axle are currently working on addressing the problem through an inspection and rectification program. model year 2017-2020 Elite II. See Attachment included.
