I know this is the wrong catagory but no one ever really checks out the s30 side of this.

I just got her up and running for about a month now.

I swapped out the radiator and put in a slim line electric fan that pushes almost 3000cfm.

I took her for a drive to make sure everything was good and about halfway through the drive i get a wierd knocking at my rear left tire. I stop to get out and see if its flat but it is not. Any Ideas what it could be? It never did this before.

 

could be a number of things, best bet is to jack it up remove the wheel (noticign if the the lug nuts are loose or soemthing) and then maybe rotat teh assembly looking fo possible noise problems. also, how did you do your radiator setup? (aka brand names) cuase i wanna get rid of the mechanical fan and get an electric one like so. how was mounting it all also

 

i got it from jags that run the fan i just used some radiator rivets

 

Possible loose lug nuts, universal joint on half shaft or drive shaft, strut loose or bolts coming loose or broken...those are a few off the top of my head. Possibly a separated tire also.

 

Yeah you can all say it now... I'm a dumbass!!! It was the lug nuts none of them were tight. All fixed now and screaming along the road...

 

OOOO and snow calls the lugnuts!!!! lol, you coulda go FAWKED up if your wheel came off, you owe me a cooke, which in turn i think i owe to murph Z32 i think... so you gotta pick up my debt.

EDIT: and wtf are radiator rivots.... thats news to me

 

they hold the fan to the radiator. They are plasic rivets that go throught the radiator core between the little fins and then they snap on the other side to hold it in place. I'll try to get a pic for ya. It was about $5 at autozone for the set.
