Only right hand nuts arerequired. Wheels for cone lock nut mounting areidentified by the lack of deep countersinks around thestud holes. Wheels are centered by the close fit of thewheel center hole to the hub pilot. Hub piloted wheelsystems are available in both 8 and 10 drums (Fig. 1) eliminate the need to removehubs when servicing brakes vs. Inboard (Fig. 2). Stud Piloted - Double Cap Nut Mounting (DCN)Inner and outer nuts on duals, or single cap nut onfront wheels locate and hold the wheels. Both righthand and left hand threaded studs are required. Atotal of 20 nuts required per wheel; 10 inner, 10 are identified by spherical countersink aroundbolt holes.

Axlesare still available with manual slack adjusters, however these axles should only be used on 121-exempt vehicles. Ultimateresponsibility for compliance lies with the vehicle manufacturer or axle AXLE KITSOur Axle kits are covered by part numbers made up of codes . These codes represent various axle components are loose; however axles can be ordered with components assembled by simply adding an "A" to thebeginning of the part number. (Example: AS08-1309-2008-09)Because of the wide selection of axles available from stock, orders for assembled axle kits can be filled on short over the listings on the following pages. If you need more information, call can help!

Make sure it works with the axle being example calls for a set of ten-stud hub and drum assemblies with RH and LH studs (1013824 & 1013825).ABS RULESB ecause of government mandates, all trailers built after March of 1997 must be equipped with ABS.

4 On replacement axles,care must be taken to equip the replacement axle to match existing MERITOR AXLE SERIESA rvin Meritor, one of the Premier Manufacturers of TRAILER Axles, is well representedhere at New Life. The Following Listing explains the types of axles and SERIESThe Meritor TN Series is the industry workhorse - an economical, standard-use axle, highlysuitable for a wide range of vocational applications. ArvinMeritor's pioneering and introductionof many unique Features and benefits have made the TN Series the standard on more trailersthan any other Lightweight Design Maximizes fuel efficiency and ability tocarry increased payloads. Integral spindles with induction Enhances strength and of critical areas, such asboth bearing journals, and integralstamped spiders. Closely controlled spindle alignment. Improves Tire Life. Available with Meritor Q or Q Plus Increases service intervals"quick change" SERIESE xtra heavy-duty Meritor TQ axles are designed specifically to endure the severe torsionalforces exerted on an axle by air ride suspensions.

5 When used as a standard suspension,however, the TQ axle also stands up much better against forces exerting downward pressureon the suspension. What that means is that the Meritor TQ TRAILER alxes are appropriate whenheavier-than-normal cargos will routinely be transportedFeaturesBenefits Thicker axle wall than the TN Series axle. Provides rugged design that can withstandstress caused by torque rod action. Standard bolt-on bushing assembly. Provides long-life, easy-to-service assemblythat can withstand the demanding forces ofheavy-duty applications. Lightest weight extra heavy-duty axle in the industry Maximizes fuel efficiency and ability to SERIESThe Meritor TP Series axle is the axle to use when you need compatibility to the Fruehauf /Pro-Par type wheel end. If this type of axle is in the fleet, wheel end components areinterchangeable with that Inner and outer axle bearings that are the same size. Reduces inventory requirements. Most TP axle brake parts are interchangeable with those featured on Meritor Drive axles.
