front end grind HELP!

Alright guys...

02 Tacoma double cab 3.4 non trd 4.10.gears man locking hubs.

Grinds bad.

Does not grind in 2wd... Unless I lock the hubs then it does grind in 2wd Hi, it grinds in any 4wd as long as hubs are locked. Was a little low on diff fluid so I drained and replaced. I put 85-140 in. No change and no there wasn't any metal pieces in drain pan.

Thanks in advanced

 

Sounds like you need to take your hubs off and clean them. I had a bolt and washer come loose in mine. Had to buy a new bolt from it rolling around in there. Solved my problem, hopefully yours will be this simple. Welcome to TW!

 

Thanks I'll look in the coming days
