may sound dumb but I need to know. I have an '04 wrx sti the garage states i need a new 1/2 shaft sssembly due to an oversized boot being placed on it and the grease/lubricants not being in contact with rotating part, I believe them as they showed me and the boot on the driver side is quite a bit larger. So they ordered me a replacement, they went to install the part and then told me they could not do so as the shaft they got for me was NOT A.B.S. compatible. Is this true or a crock? If they ordered the part from a good source and they informed this parts store that it was an 04 wrx sti, that the people would know that they all are ABS and therefore send the appropriate shaft, right? or is my car so totally different from every other STI? getting my new shaft that i ordered myself installed on Saturday so any advice info would be truly appreciated in a timely manner, thanks.
