I need to get a half inch longer wheel stud for rear wheel on my 1996 Cherokee XJ. Does anyone knows where can I find it ? Thank you, appreciated.

 

I think the front wheel studs are longer , you can see if those are long enough

 

Napa, pep boys, and possibly ace hardware all sell wheel studs. Just have to bring it in and match up the length. You need grade 8 sae or grade 10.9 metric. For out jeeps metric and sae are the same threadcount physically
