1970 T: Rear Hub Bearings…which??

[OldTodger99]

Some possibilities for re hub bearings available in Design911 site but cost range is massive, from as little as £30 a side up to £300/£400 angular contact bearings. What’s the difference apart from cost? I’m not tracking the car

 

[911UK]

Different types, different costs

Different types, different costs

Maybe others on the forum have some engineering insight to my question? I expect there’s more to say

We are talking rear wheel bearings? £300+ each? where have you seen that? OEM version about £40

Few links to example parts re hub bearing:

Then there’s the cheap one £30 a side

Those are oversize ones, is your hub fecked?

 

[OldTodger99]

Nope, in good shape, bearing measures 75mm x 42mm (ID) x 37mm (give or take). 1970 911T stock, I’m assuming the trailing arms are also stock

 

[PeterHoward]

OK, so why are you looking at o/s?

You need part number 99905303400

 

[OldTodger99]

Frankly I wasn’t aware I was looking at oversized bearings . I simply measured the hole that needs fitting with a new bearing, no other science behind it……I’m on a learning curve to say the least! Still not clear on the difference between a £30 bearing and something costing between £250 & £400. Few pics of trailing arm if it helps…

So this product would be suitable? Numbers cross reference correctly unless you think otherwise?

[PeterHoward]

Yes, thats what I would use. The O/S bearings are somewhat limited in their use, hence the price!

Thanks for guidance
