To determine the correct size, you should:
* Check your owner's manual: This is the best place to start. It might list the specifications for the axle nuts.
* Consult a repair manual: A Haynes or Chilton repair manual for your specific year and model will contain this information.
* Check the nut itself: If you can safely access the nut without removing it completely, you can often see the size stamped on the nut itself. Look for numbers and/or letters.
* Take the nut to an auto parts store: A knowledgeable parts person can measure the nut and identify the correct size. This is probably the best and safest option if you can't find the information elsewhere.
Important Note: Working on your vehicle's axle requires caution and proper safety procedures. If you are not comfortable performing this task, it is best to take your vehicle to a qualified mechanic. Improperly torquing the axle nut can lead to serious damage or injury.
