The Auto in my EF falcon has leaking driveshaft seal.
The seal itself looks easy to repace, but I've been told that I should replace the bush in the rear housing of the transmisson as well. What is invovled in replacing the bush - Can I get the rear housing off with the tranmission still in the car??? |

basically jack car up...
remove the 4 bolts on the uni joint and mark it so it gos back on the same was as it came off ( liquid paper is a good aid ) the take the drive shaft out the seal shoudl come out with some force... and replace with new seal carefull nto to damage it a socket the same size can be used to "tap" the seal back in then re install the drive shaft easy as!

Be sure to buy the V8 Bush they are much stronger and suit the 6cyl trans also, I believe they are made of bronze.

its the extension housing seal, i wouldnt bother with the internal bush. when removing the drive shaft make sure it is aligned the same as when removed to keep a system balance. there will be a yellow dot on both ends of the shaft. copy the dots onto the diff flange and the transmission spline (not the extension housing) the 4 bolts on the rear flange will be tight and you will need an 18mm ring and i thing the other is a 15mm.

u dont need to mark it the drive shaft doesnt have a master spline...just put it on any old how it fits...put the car in N so you can turn the gearbox and you are fine...pfft i did mine months ago n i put it in so it fitted, not to match any marks...

Sorry ndroo but im a quality officer for the company that makes the shafts for ford. The dots represent the lighter side of the shaft after balancing, transmissions and diffs are not perfectly balanced so to improve the system balance the dots are lined up with markings on the trans and diff. with the BA its the same princible but the driveline is further balanced at ford. Just one of the advancments of the BA series, it also goes for the territory.

mmm...well...the difference isnt enough for me to worry about lol...maybe it'd be a problem at really high speeds but it seems to be able to withstand it fine without any vibrations.

ok so all thing being balanced can you explain to us how a ballanced shaft can have a 'lighter side' it doesn't make any sence at all, if it has a lighter side it would not be balanced and you people are not doing a good enough job. the other thing is that if you make the shaft straight in the first place they don't need to be balanced with wieghts. We all know that these wiegh you people insist on using fall off al the time and the shaft in questoin in this thread is probably out of balance now anyway so the dot don't matter. |

thanks disco frank you exlpained it well, because the shafts are mas produced we have a min spec set by ford. it would be impossible to get a shaft "perfectly" balanced as we would spend atleast 10min a shaft, the limit we have now is 4min max. Even the engine cranks are balanced!!!

surly tho a more 'quality' product wouldnt need to be balanced. They say its expensive to produce them to such high standards, higher than standard..but thats only so because its not 'standard' to produce them like that standard...if we have learnt anything its all things mass produced are cheap...and just because they are mass produced doesnt mean they are not quality. Standards of today are the above standards of yesterday...

up to about 4 years ago 1 piece shafts were never straightened only balanced, but as the cars internally got quieter the outside had to be made quieter. so the 2 peice shaft was introduced. shorter lengths of tube meaning less if no flex resulting in vitually no vibration and noise. the current alloy shafts are straightened so dont stress ppl if you have a BA ute or wagon!!!!
