Hi I own a 99 2.4 frontier...
I had a code p0304 that I finally fixed thanks to this site so thanks.. It was my egr ports..
Before I figured that out I dropped tank cleaned it out bc it had been sitting for a few years and it was Rusty baaad..

I took intake off cleaned all that out, put it back on.

Ok while all that was going on I noticed my charging belt kept going bad. So today I'm trying to figure it out I notice my harmonic balancer is wobbling...

My question is, could it just be loose? Before I got it the guy had just put new timing chain etc so maybe he left it loose.. it looks like it's wobbling more in the back of it.. it's made the a/c idler pulley bearing go bad too.. errrr I'm getting frustrated.. it straightens out when I give it gas.

And on top of all of this I have a p1776 lol.. I'm thinking bout getting rid of it.

Are you a manual or auto.

Can you check the big bolt that holds the pully on. Is it loose, can you tighten it. Put in 5th gear to keep the crank from spinning if you are manual. Suspect auto and previous owner did not have a holding tool and never tightened in properly.

It's auto.. he bumped it on with impact.. going to check tonight. Do you know what size the head is? I don't have large sockets right now I'm in the process of building my tools up. 22 maybe?

Get this set. Works well.

Nissan crank pulleys have 2 holes in them. There are special tools (pin spanner) that uses these holes to hold pulley and keep it from spinning. You can make your own. Google for ideals.

Could be 22mm, but probably 27mm. The problem with the crank bolt being loose is that it sometimes will cause the keyway slot in the end of the crank to get damaged, which puts the crank pulley in the correct spot in the crank before the bolt is tightened. If it gets damaged and you don't get the pulley in the exact position, the timing marks will be off.

Well it's good now it was just loose.. I used vise grip to hold pulley to tighten. No more wobble. Thanks

It was a 27.. 1-1/16 fits good and snug though
