Exhaust/driveshaft issue during pinion seal install HELP!!!

**clg82** · 04-07-2016, 07:41 AM

Hey everyone going to knock out my pinion seal that's been leaking for the past year tomorrow....got all 4 wheels up in the air as well as the wheels off and after crawling under there, there's no way in hell i'm going to be able to get to the driveshaft to remove the bolts to get to the pinion nut itself! Look at the picture the driveshaft is flush against my exhaust....I hear no noises at all when driving like their making contact....is this because the weight is off the rear wheels? how do i keep this from happening? picture here:

Is the rear under load or free hanging?

Meaning are jack stands under the axle or under the body?

Axle is free hanging...I have all 4 wheels off and 4 jack stands under the body.....should there be weight on wheels so that the exhaust will move away from the driveshaft?

Correction, put the stands under the rear axle, this will raise up the drive shaft and rear away from the exhaust.

will do...have you ever run into this problem before? it must be because the rear axle probably never sees this amount of droop and that is why it is coming in contact with the exhaust now? is that correct?

Yes, the muffler shop did you no favors by running it this tight. It's one thing to keep it tight to not hit objects but another when it prevents you to work on other components.

ok I appreciate the help...will let you know how it goes when I put the stands under the axle.

Damn... what the heck were they thinking routing it like that? I take it you do not see any rub marks on the drive shaft from contact? Contact would only be an issue on something like a shallow dip or hump in the road where the body would rise up on the suspension to the full extent of the rear shocks.

nope no rub marks that I can see....will probably end up using the jack stands up under the axle and doing it that way....yeah not sure why the exhaust shop would do it that way....any way I can reroute the exhaust on my own?
