All,

I have a leaking front diff on my M38A1 have replaced the seal twice and RTV'd in all the right places but still have a pesky leak. Searched the forums and mention was made of sleeving using a product called Speedi Sleeve, this is something I have not come across before here in the United Kingdom.

Would somebody be kind enough to give me a link to what I would need to further troubleshoot this problem using the sleeving method... and a possible purchasing point.

Any help would be greatly appreciated.

Regards

Nic

Don't know if these folks sell in UK but here are 2 websites. I imagine that they use them in UK, might be another language issue, you all call them something else.

I also search the UK ebay for speedisleeve and got some hits for some.

I don't know how bad your yokes are but the seals could also be the problem, if they don't fit tight on the yoke, prior to pressing them in the transfer case, etc, if they are loose then the seal might be the problem. I have been sold some that are made in china and they don't fit corretly, i.e. tight so they don't seal. I started only buying them from some of the more reputable parts dealers overhear like Midwest Military and Mullins jeep parts.

Hi Nic,
And this might be helpful: http://willysmjeeps.com/v2/modules.php? ... ght=speedi

Good luck!

Thanks for the quick replies guys it's appreciated.
I always buy my spares from John at Midwest and this is where I purchased the seals from. Back one worked a treat first time no leaks whatsoever, front one putting up a fight will continue to persevere.

Thanks once again fellas.

Regards

Fantastic.. Once again Thank You!!!!

Metal shaper's video pretty much tells it all! Here's a link to my own build post if you want to see the damage that I had on my yokes:

In the end, I put a Speedi Sleeve on all four yokes on my Jeep, both transfer case outputs and both differentials. After reading some mixed reviews on the quality of reproduction yokes and seeing that the damage on my yokes could be completely covered by the Sleeves, it was an easy decision to make.

Here's an Amazon link to the Speedi Sleeve SKF 99156, which are actually quite pricey... Not sure if Amazon UK is different:

I actually purchased all of my sleeves from Rock Auto for almost half the price of Amaon, but again I don't know if the ship to the UK:

Thank you for your advice and information.

If you have a rather deep groove in your yolk, you will want to use Loctite 660 to fill in the groove which will keep the thin sleeve from being pressed down into the groove from the pressure from the new seal.

Thank You will get some.
