Part Numbers in that Kit sound the right parts... I need a confirmation before pucrahse too, If any body help please.ThanksDid you or anyone else end up purchasing Kit-ST215 for your Rav4? I'm wanting to use this kit for my 2007 but want to confirm it works with this year. Thanks.
What about the dust shield ? anyone bought one ? I found a Toyota service bulletin that shows the rebuild of these. Seems they want you to buy the Cover Sub-assembly (aluminum casting w/bearing installed I presume),Dust seal and Deflector.
I have an extra (replaced once already and kept old parts, before realising a warranty was in place, now problem has resurfaced and no Toyota coverage !!). I have pushed out the coupling body and bearing, seems all I need are the bearing, seal and deflector. When looking at the pics. in the service bulletin it looks as thought the housing has been changed somewhat hence the need to replace the old style.
I'd still like to buy the 3 pcs. and see if I can make this work. So how does one find the parts ? The P/N's are listed in the bulletin.
BTW...…. the bulletin is T-SB-0080-13
Sure so here are my thoughts.Is the oil flow to the front blocked at the packing seal, or is the gear oil supposed to get into the electromagnetic clutch housing? Can anyone explain how that clutch is working without a power source? And thank you very much for your responses... I wish Toyota would supply better diagrams and exploded views in their bulletins.
I've ordered the kit and am waiting for it to arrive. I will post back once I get a chance to install it.
But isn't the purpose of the electromagnetic clutch to engage/disengage the 4 wheel drive on demand from the computer? If it's just a direct drive, then why bother having it there at all?Sure so here are my thoughts.
1) Power is coming from the Driveshaft. The driveshaft is connected directly to the Coupler and spins it. Coupler goes into the Rear Diff and power will get distributed to the wheels.
2) For the gear oil, I think the best answer is around page 8 on T-SB-0080-13. To me, yes there will be oil coming out of the Rear Diff when you detach the coupler, but that is only supposed to go inside the interior of the coupler housing (reference T-SB-0080-13) . When the big bearing came out (Front one) the bearing wasn't oily.
If you only drove straight and all four tires had the same circumference you could direct drive the rear wheels. But there has to be some way to let the rear wheels run slower than the fronts on cornering since they take a shorter path. And tires are rarely exactly the same circumference either due to wear and air pressure.But isn't the purpose of the electromagnetic clutch to engage/disengage the 4 wheel drive on demand from the computer? If it's just a direct drive, then why bother having it there at all?
In two hours I removed driveshaft then coupler. Removed noisy front bearing. Replaced with new bearing and put it all back together no more noise nice and quiet. 18$ for the bearing you don't need to hassle with the warranty or dealers. Simple job.
