This has been a bit of a saga for me. The wifes 98 SI had a wheel bearing starting to go on the front passenger side. The cheap and quick side of me decided to just swap out the entire hub/knuckle with one from pick n pull ($30) vs buying the bearing ($140) and pressing it on and off.

Long story short I grabbed a knuckle off a 94 integra (which also has the larger 10.3" rotor) installed it without issue only to realize a few days later the integra knuckle is taller then the SI knuckle. Which caused the car to ride 1 1/4" high on the passenger side which also changed the camber. I then went to the junkyard and grabbed a 2000 EX spindle and swapped it for the integra one. The car however is still sitting high on the passenger side by 1/2". I jacked up the car and tried measuring/comparing the knuckles from side to side and they do appear to be the same length/height. However I cannot be sure unless I remove one and take exact measurements. So now my question is, are 2000 EX and 98 SI knuckles identical or different castings?

civic gurus please help me out here. I have been googling for two days and it's pretty tough to sort fact from "yeah it should fit"

Thanks
Andrew

 

98?

 

1998

 

canadian civics are not my expertise, but i am 99% sure they are the same.

 

Ah, Canada, Didn't know there was a 1998 Si.

 

oh i see now, that's why I was always reading 99-00 SI. Didn't realize it wasn't released in the states in 98.
Thanks eghatch, appreciate the input.

 

canadian si= us ex. canadian sir= us si. your ex had the d16y7, whereas ours has the y8. i have no idea if your ex got the larger front brakes or the smaller lx/dx brakes that came on y7 cars here.

 

the acura el is the same chassis with the vtec engine, its brakes would work. digging deep into useless knowledge bank here.

 

Just to be 100% clear, we are talking about a Canadian 1998 SI, correct?

If so, they are the same.
In Canada SI= US EX
SIR= US SI

 

It is a canadian SI yes indeed. Thanks for the info gentlemen. That cleared up a lot of stuff for me. It did come with the bigger brakes. I didn't realize there was such a thing as a 2-door EX aka canadian SI
thanks again, appreciate the help.
