Maybe Mopar is right!

autoparts123.com shows a timken hub kit for 66.48 w/free shipping. They are sitting on the bench ready to go in our ACR this week. The bearings are actually FAG if I remember correctly.
autoparts123.com is actually parts plus america web site. Nobody has been able to touch their prices on anything!!.

I paid $96 canadian for an SKF to go racing this weekend. It looked like an acceptible piece, and survived a very enjoyable and enthusiastic 2 1/2 hours of track time. I figure 10 or so hours, then bin it and put another on. Another couple hun every 4 race weekends is, sadly, a pretty small part of my budget this year.

I phoned my Dodge dealer this AM to tell him to drop the backorder on the MP kits, and order me the hub only. He phoned back and said they won't cancell the backorder, as they are in the pipeline somewhere. I will let you guys know if and when they show up.

When the Mopar Hub/Bearing assy went disco we started using the SKF with acceptable results. With any of the hubs, proper torque and adherence to a strict replacement schedule is key.

Last year at Nelson's Longest Day, we ran a set of Mopar hubs 24 hours without re-checking torque with no problem but in that situation there really wasn't much in the way of heat cycling like in more typical sprints.

Hi, im new to the forum and stumbled across this thread. I have a 95 ACR that i run in ITA in the PA hillclimb series. I have heard about the hub problem but never quite understood the severity of the failure. You guys have me freaked out now. When something fails on the hills you usually fly off into the trees because we dont have a nice runoff area like the tracks do.

So, from this thread it appears i only have two options. Get the SKF hub from Napa or the Timken from autoparts123. To me both are respectable brands, it seams hard to beat $67 bucks for the bearing and the hub for the Timken. Does the SKF come with the bearing too?

How often should i replace hubs. It would take 10 years of hillclimbing to accumulate 10 hours. We have about 10-15 runs a weekend and they are only 1-2 minutes long. I do about 10 events a year.

I have stock ACR suspension, poly bushings and run auto X V710s tires, sometimes RA1s when we do track time trials. Only twice a year.

As soon as i get some more money i will be taking some drivers schools and joining yall on the track, but for now its the affordable scary as sh*t world of hillclims for me. THanks for reading.

My MP ACR hubs and bearings showed up yesterday. $105.08 Cdn each on my doorstep. When I priced the hub alone, it was over $200.00.WTF? I do have a tame dealer who sponsors me, but retail on the invoice was $135.

Anyway, I got 4, which should do me for quite a while.

Any feedback on how the Timken hubs have performed in your car?

Did you slap a micrometer on those jokers and see what the flange size is compared to the Mopar and/or NAPA hubs?

[worthyking]

For anyone that's interested I spoke to Timken and found out that their hubs are 9mm thick. They are manufactured by Bearing Technologies in Avon, Ohio. BT is the ONLY manufacturer of aftermarket wheel hub assemblies in the US, so I suspect that these are the same hubs as the NAPA/SKF ones, as NAPA does claim that their 9mm hubs are made in the US.

so those of you that check your axle bolt every race...does that mean you remove the cotter pin and the keeper every time or just removed them all together.

I have a set of MP hubs on my bench; i am going to get them cryo-frozen before installing them.

[worthyking]

Yep, take the cotter pin & keeper off, check the torque, and put em back at least once every race weekend.

We run cryo'd Timkens on our car.

[Kolin Aspegren]

I leave the pin off all the time and torque after every session.

I ordered a set of Timken hubs and when they arrived they came in an SKF box. So, that would confirm my suspicion that they are the same hubs as those NAPA sells. I put a micrometer on them and verified that they are 9mm thick at the flange.

I had them pressed onto the knuckles and cryo'd both assemblies (hub,bearing,knuckle). Ran them last weekend in an enduro and will run another 4 race weekends or so then replace.

I'm thinking of sending them to a metalurgy lab when I pull them off to get an analysis done to find out how much fatigue has occured. I am interested to know if the cryo makes a huge difference. Anyone have a hookup to a metalurgy lab who might want to donate an analysis for the sake of research?
