so my wifes 2001 suburban blew the pinion bearing this weekend, long story short cant find a pinion seal for it? Carquest, advanced, napa, autozone, pepboys and oreilly all tell me its a 710506 seal. Problem is the 710506 has a bigger hole than my yoke. My shaft is 1.940" and this seal is 2.188" so it does not seal.

Anyone know why gm did this and what is hell is the right one??

2001 suburban 1500 4x4, 5.3 with GM 8.625 rear end.

Yes I have seen this many times. There are 2 different designed seals. One has a lip on the edge and the other is flat. Both with a different I/D. I would suggest going to your local dealer to get the right seal. Bring the old one if you have it.

 

You said 4x4 But didnt mention which one Front or Rear Pinion???
Front with 1.94 Id. is Napa part number NOS 19428

 

rear!

 

Look at either a 19314 or a 19273 They are from the earlier ten bolts but the ID is right, one has a flange the other does not.

 

thanks for help. my local driveshaft shop fond a seal from NATIONAL #2043.
dealer only sells updated yoke with seal, $150. Older yoke has been dropped!

I went the cheap route with just the seal!

Found this at work, listed under a 97 1500 pickup.

Sorry it was too late

 

im late as well but all the goobs you talked to that gave you the 710506 number were giving you a seal for the 9.5" ring gear! i kno bc i work at a oreillys and just swapped gears in my 14 bolt 9.5" and went and checked before i bought any! they just didnt look as good as they should have!

 

710506 is not for the 9.5". I work for O'reilly too

710507 is for 9.5"
710508 is for 10.5"

 

wow goob moment my bad 710507 is for the 9.5" DUHHHHHHH!!!


i just realized what i put! now i feel smart
