Jay m A Posted February 23, 2004 Posted February 23, 2004 Hi - I've always said 'if you're not sure - ask' even if its a dumb question On fitting new wheels this weekend I could wiggle the rear wheel ALOT, quite shocking really since it passed its MOT last month. Checked the hub is secure, checked the wheel was fully mated to the disk etc and still alot of wobble. Anyway, being new to all this I need to source the correct bearing, the car is a SEiW built in 99 with alloy hubs. I assume its a Sierra rear wheel bearing, but any particular model? for example is a XR4 bearing different from a 1.8L Any help greatly received - especially part No and cheapest supplier thanks Justin Quote
neilwillis Posted February 23, 2004 Posted February 23, 2004 Do a search, this has been discussed before. Also, what rear end do you have? Independent, or live axle etc etc Quote
Jay m A Posted February 23, 2004 Author Posted February 23, 2004 I've done the search - still confused, some say sierra, some say its a special Westfield bearing. Or, the nut needs tightening - 250 lbft, blimey! Quote
Blatman Posted February 23, 2004 Posted February 23, 2004 I'd be checking the hub nut first, for sure...... Quote
Keith the Teeth Posted February 25, 2004 Posted February 25, 2004 Probably an obvious question but you are sure that it is the bearing? Play in the rear can also be a shot rose-joint. Quote
SteveC Posted February 26, 2004 Posted February 26, 2004 .....or play in the wishbone bushes. Have you hilighted that the play is at all angles around the wheel to try and remove the non bearing possiblity? Quote
Jay m A Posted February 27, 2004 Author Posted February 27, 2004 Thanks for the ideas. Yep, play is at all angles, and when I said 'hub' in an earlier post I actually meant 'upright' I've purchased a 41mm socket and 2' bar and will be looking at the car Saturday morning. I've just found out the car has been running on 7" wheels with ET19mm (should be 35mm), which won't help the bearings, by how much I'm not sure though. Quote
Blatman Posted February 27, 2004 Posted February 27, 2004 I doubt the offset would unduly stress the bearings, so ignore that as the cause........ Quote
darthurs Posted February 27, 2004 Posted February 27, 2004 If it has rear disks, take off the calliper and pads and see if the disk touches the carrier bracket as you pull on the hub. If the disk touches the carrier bracket then it is most likely the bearing or the hub nut being lose, if not I would look else where. Dan Quote
jeff oakley Posted February 27, 2004 Posted February 27, 2004 The rear hubs look to me to have the same bearings as the front steel fabricated ones westfield used to produce. I sorted these out for Andy @cat and these turned out to be volvo 340 bearings. The rear hubs are alloy and need to be heated to remove the bearings according to westfield otherwise you may damage the hub. Ither way once you have then out take them to a bearing supply company or a good motor factor with an adult on the counter(not Halfords) they will take the bearing number off the casing and will be able to get you the correct bearing. Fitting is done by warming the hub in the cooker whilst having the bearing in the freezer, one expands the other contrats and slip together easily. If in doubt take it to westfield who will do the job for a fee without damage. hth Jeff Quote
Carl Posted February 28, 2004 Posted February 28, 2004 I've just found out the car has been running on 7" wheels with ET19mm (should be 35mm), which won't help the bearings, by how much I'm not sure though. This will effect the bearing life, however due to the light weight of the car I suspect if fitted correctly the bearings are very over specified. A dead give away to knackered bearings is smooth rotation of the wheel, not wobble. When rotated by hand slowly. is it smooth and noise free? Yes- No- Works 95% of the time. Quote
Jay m A Posted February 28, 2004 Author Posted February 28, 2004 The nut was indeed loose. Thanks for all the input Quote
Blatman Posted February 29, 2004 Posted February 29, 2004 This will effect the bearing life, however due to the light weight of the car I suspect if fitted correctly the bearings are very over specified. Do you work for the government? Quote
Blatman Posted March 4, 2004 Posted March 4, 2004 Quickest U-turn I've seen in a while......... Sorry..... I'll explain..... If the bearings are over specced, offset will have no effect on their life. If they are under specced, or poorly fitted they'll fail anyway. There aren't hundreds of cases of wheel bearings failing, despite the fact that there are all manner of offsets used on the thousands of Westfields in use. Therefore, the anecdotal evidence would suggest that the bearings are pretty OK, no matter what offset's are used, ergo, offset will not affect bearing life......... Disclaimer. This is NOT a rant, just a bit of light hearted teasing OK.......... Quote
