Rubber coupling Propshaft 2009 ISF


Recommended Posts

Hi

I have some cracks forming on the rubber coupling that connects the propshaft to the differential on my 2009 ISF, Lexus are saying I need to replace the propshaft!!! Any ideas where I could get a coupling from? Thanks in advance. Tim

Hi Tim,

Have a read of this thread on the American forum.

The propshaft rubbers are also known as guibos

Looks like we can use Supra one's if we can still get them.

The Supra ones are also used on the Lexus SC430 5-speed (and GS430/LS430), which was sold until 2005 so hopefully the parts are still available. 

On the 6-speed SC430 they switched to the same situation as the IS-F, only supplied fitted to the whole prop. Not sure why they did this, maybe they balance the entire prop with the couplings attached.

@ColinBarber From reading on the American forums, the couplings are bonded on the propshaft. However a few owners stateside say they do come off with no bonding visible, at least to them. 

With the part being used that widely, I reckon they are still manufactured. I'm guessing with some confidence that it was probably used on the GSF and RCF as well. Stands a chance they use the same coupling on the LC500 V8's. It's cheaper to use existing products that work, than develop and use new.

Yes, it certainly looks the same as the one used on the GS F and RC F. The problem is that the part isn't available on its own - there is no part code.
