Pinion Seals, D44

[ChEwBaCcA]

Where am I going wrong here? Had a seal replaced along w/ new gears and full rebuild last year. Seal was Ok for a while and then started to leak"about 2 months" after the axle was rebuilt.

Went to replace the seal last weekend.."a year later" .its leaking worse than w/ the 1 year old seal!....also replaced my front d30 seal , same seal same manner and its fine.....

any tips:? its leaking from the seal not the metal to metal edge around the housing.

Im about ready to put a zip tie on the seal to tighten it up...seems to me the seal doesnt make a very tight fit on my yoke.

Its not overfilled....the pinion is tilted up some to keep it inline w/ my CV shaft

It was a Timken seal , so its not a $2 cheapo special

The spring goes on the inside towards the bearing no?

If it's not related to the change of angle, you might have a worn shaft. If so you might want to look into these sleeves that are made specifically for worn shafts......might still help you out even if the shaft is not worn.

But this is just a pinion yoke issue, seems to be easier to buy a new yoke? Or could this be a bearing/angle issue? The yoke while tight w/ nut didnt seem to move...or maybe its moving around under load?

Sorry, of course you are correct.....a senior (almost) moment on my part. I really didn't think it through very thoroughly.
