1965 Buick Skylark Wagon...Big Brakes & Big Bearings.....Can someone give me an idea of cost to have old wheel bearings removed & new ones pressed on axels ?
Also, can someone verify that the bearings are larger on Skylark 'Sportwagon" than on standard Skylark Wagons. The brakes are 2 1/2 " wide as opposed to 2" on the standard Wagon. If yes, does anybody have part # for bearings? Thanks
Sportwagon and Gran Sport use the larger RW507AR. Plain Skylark and flat-roof wagons use the RW507CR. The 'R' suffix means it includes the retainer, without retainer would be RW507A.
wkillgs: Thanks for your response. Do you have a suggestion on the easiest place to find the 'AR' bearings. I'm having problems finding them.
I just sent an original New Departure RW507AR to Florida. They are not as rare as the GR bearings. I have seen them pop up for sale on eBay.
I paid $160 to have one bearing & seal replaced on my 68 GS400. That was labor only, I supplied the bearing & seal.
wow AUTO ZONE had them??? That is very weird... Jim 160.00 just for labor is a tragedy... man how can they sleep at night??? so 320 for BOTH axles to be done...OUCH!
Ok so just to clearify some info in my own head, can someone tell ne the size differances between the rw507ar,cr,gr I have an 8.2 appears to be what I can find out of a 69 Pont a body. I have no axles for this unit. The axle I thought would fit are from a 68 gs 400. They gave 507gr bearing....the bearing are large in diameter to go into the housing but the axles spline into the carrier. I have been looking but getting differant info. If someone get or has the correct measurements for the id,od, and width of the ar,cr,gr bearing I would love to add this info to my files for use later if needed Also do these all take the same inside seal
Yes,all take the same inside seal,8594S. Here are your bearing specs for the 3 bearings: RW507CR = 1.380" ID 2.747" OD RW507AR = 1.380" ID 2.890" OD RW507GR = 1.437" ID 2.890" OD As you can see,if you had a 68-69 GS housing,and you don't have axles,or tore them up with a bad bearing,you could use the more common shaft,and use the AR bearing to make it all work. The AR bearings are somewhat rare,but not as hard to find as the GR bearings. Russ Pitts,in Florida,is looking for a set of original 68 GS shafts,if you have them. Maybe he will see this and chime in.
The RW507GR bearing requires a different seal since the axle is a larger diameter. Used in 66-68. GM pn is 1376776. The Buick Farm has nos ones available. The seal was available from SKF, #14088, but may have been discontinued. Another option to use the 'A' or 'C' bearing in a 'G' housing is to fabricate a bushing to fit the smaller bearing into the larger housing.

My shafts and axles from the 68 are in great shape, but for some reason about 3/16 maybe a 1/4 inch has been cut off one. Still splines in with no issues, not sure why this is or happened or when
I'm not so sure this true. The axle is only thst thick right at bearing area and retaiming ring, it necks down right after that, so the seal could be the same size.
I remember using the same seal for all of them. I think the axle diameter is the same on the seal area for all three,then is larger for the bearing area,on the 68-69 GS. Ben,if you have one of those loose,can you post a picture of that area,or can you mic the seal area?
Axle from '66 GS..... 1.411" at the seal area. The 8594s seal is spec'd for a 1.35" shaft, 2.571" bore. I'll have to search my books for the specs for the other seal, not finding anything online.
