Torquing the lug nuts on my Crusader 295rst.

After only four thousand miles, I had a blowout on my right rear tire. I suppose I overreacted but rather than keeping the D rated tires I went up to a Gladiator which is E rated.

During changing out all four tires, we could not read the torque specifications for the Dexter axle which was listed on a sticker above the axle. Sorry for all the rambling... so I'll get to the point. Because I had a brain dump or something in between we set the torque at a hundred and fifty foot pounds. I believe this is excessive. Can anyone tell me if they think I have damaged the lug nuts and studs? And what should the lugnuts be torqued? What should I do?

I'm out on the road and at the mercy of the tire dealership. So any help would be greatly appreciated.
  • My 5,200 lb, 6-bolt axles are torqued to 110 lb ft on Al rims.

  • Time to download materials so your not "at the mercy" of anybody.



    Make a binder for everything you have and keep it in your RV. And yes, it is amazing what some shops do compared to the manual.


    Here's what I found, it might help maybe not. (copied and pasted)

    Prime Time Manufacturing Fifth Wheel English 2015 http://idn.tweddle.com/forestriver/manual?itemtype=UG&brand=Prime_Time_Manufacturing&model=Fifth_Wheel&language=EN_US&year=2015&market=US&idn_session=6ubuchkks8lpd1nstpjarl3ro0



    Typical torque stages

    1ST STAGE 20 TO 25 ft./lbs.

    2nd STAGE 55 TO 60 ft/lbs.

    3rd STAGE 85 TO 95 ft/lbs.


    Note:
    Start all lug nuts by hand to prevent cross threading. Wheel nut torque requirements vary depending on the size and manufacturer of the wheel. Always use the wheel manufacturer's recommendation but do not exceed 100 ft/lbs. on 1/2 inch studs, or 130 ft/lbs on 9/16 inch studs. Unless otherwise specified by the wheel manufacturer, use a final torque of 85-95 ft/lbs.


    Note:
    It is recommended that wheel bearings be repacked yearly.

    DANGER
    Be sure to use wheel nuts that are compatible with the coin in the wheel. Improperly torqued wheel nuts can cause the wheel to separate from the wheel mounting surface during operation. This could result in property damage, serious personal injury or loss of life. Do not over torque.
  • If you have 5/8" studs, which you probably don't, 150 probably would be OK. If on the other hand you have the typical 1/2" studs 100 to 120 should be more than enough.
    I have 9/16" studs and they are torqued to 120 to 130 per the wheel MFR spec.
    If you have Steel Wheels it may be different, I'm only familar with Alumium wheel specs.
  • You didn't mention what size axles you have, but I am guessing 5,200, or 6,000.

    I have 5,200 six bolt axles on my FW, and I torque the nuts to 95#s.

    You may have caused some stretch to the studs, but if you did not strip anything, you may be alright. I would back them off, set the torque to 95, if 5,200# axles.

    At this point, you need to recheck torque often, as you should after any removal of the wheel. If the nuts stay tight, after several times tightening, you should be okay.

    I would continue to check torque on a regular basis, as you should anyway.

  • Not to sound like Captain Obvious, but do you have the Dexter manual for your axles? The torque specs are listed there. Alternatively, if you know what axles you have, you can look the manual up on line. But I don't think 150 ft pounds is too excessive. I have a small trailer and the lugs are torqued to 120.
