Hi Greg.
That picture shows the nut going straight down to the hub. No spacer/washer was fitted on either side. The hub should be as shown on the parts diagram above, with the spacer/washer under the nut.
When l put the washer onto the drive shaft the nut can only go on about halfway before bottoming out.
i can't really see if the nut is directly against the drive shaft or if this is a recessed spacer, but my car SEEMS to look the same as your original photo.
HMMMM seems l've lost about an inch of thread.... The wheel picture is as l first saw without washers l bought the 2 washers above because they seemed to be missing.
****, how does that happen ?
the photo of my car seems to look the same as the photo of your car, with the same amount of exposed threads. Are you sure that you didn't already have the spacer / washer in situ in that first photo and that it had just stayed wedged into the hub outer flange plate when you disassembled the whole thing?
No washer was present. l stripped the complete hub, regreased the bearings and painted the hub. I am wondering if the abs cog was put on upside down ! would that account for the lost thread ?
Does your washer look like the 2 in the picture above, rounded at the hub side or flat ?
Forgive me for asking again, but are you sure that the spacer / washer (Part 13) isn't the silver / yellow coloured item on both our cars under the nut? If it's not there, surely the wheel stud flange would just be able to slide off over the nut? I just assumed that when you first disassembled it and removed the nut, the wheel stud flange then slid off with the washer / spacer tight wedged tight inside the flange, and you've now reassembled it complete with the washer still intact in the flange. Does that make sense?
Hmmm Thanks again Paul
l understand the question and i'm 55% sure that l would have seen that when l derusted and painted that part. BUT !!! anything is possible, it sure is worth another deep look inside as that would make sense of the short thread. Is that washer steel and could it have rusted to the hub......... now i'm wondering. Although my nut looks like its in deeper than yours. I will take measurements ...
For the sake of 10 mins, I'd suggest it's worth removing the nut and see if that is the washer and it can just pry out. Our photos and exposed threads look too similar for me to think that isn't the washer in situ.
Well Paul, you were correct again They were indeed hidden under the new coat of black paint. I managed to free 1 off. the other refused to budge. But now l know they are there.
Thanks again
Malc
Glad to be of some little help! I can't take any glory because it was just a guess because mine seemed to look the same as yours. Not a job I've done, but at least I'll also know what to look for when I do it!
Yes, I believe you're right on the late outboard disc cars. They don't use a splitpin arrangement like the earlier models; I think the nut has a helicoil and a high torque setting. If one resuses the nut, it could probably weaken the heilcoil.
