How do I know if I need plastic or metal clip without looking at it? Crappy weather no garage. 2001 3.4 both are available for purchase and say they fit. Advance Auto.

 

If I am reading the descriptions right, it looks like you should be able to determine which one you need by reading the RPO codes on the drivers door. I highlighted the RPO codes in bold.

ACDELCO Part # FW293 {#88964168}
HUB,FRT WHL(W/WHL SPD SEN) 2ND DESIGN; WITH PLASTIC SENSOR WIRE W/CLIP, FOR 1ST DES SEE 12429204; 2 DOORS; w/BRAKE,HD DISC/DISC(JA9) or BRAKE,LT WGT,DISC/DISC(JB9) or FRT & RR DISC ANTILOCK BRK(JL9); LH AND RH

ACDELCO Part # 2017 {#07470017, 12429204}
HUB KIT,FRT WHL 1ST DESIGN; WITH STAINLESS STL SENSOR WIRE SPRING CLIP, FOR 2ND DES SEE 88964168 OR FW128; 2 DOORS; w/BRAKE,LT WGT,DISC/DISC(JB9) or FRT & RR DISC ANTILOCK BRK(JL9); LH OR RH, INCLS BEARING, MTG BOLTS, SENSOR

The clincher seems to be the JA9 code which necessitates the plastic clip 2nd design.

 

I have no JA9.

 

The one I need then is the metal one correct?

 

Since you don't have JA9, the HD brakes, you can actually get either one, as the other 2 braking packages are compatible with either part.

You could probably use the AC Delco part number and find a Timken assembly online for cheaper. That's what I did when I replaced the left front hub assembly on my 2005.

 

Thank you.
