Two weeks two problems. Last week I had to replace the fuel pump and now I noticed a vibration in the rear end upon accelration. A co-worker following me home the other day said he noticed a puff of smoke from under the vehicle as I was going up hills.
This morning I looked under the diff and saw a leak from the front pinion seal. I have never tore into a rear end on a blazer before. I was wondering if I need any special tools before I start or if anyone has any advice before I get myself into a pickle.
I feel I was pressing my luck last week by cutting a hole in the bed to change the fuel pump instead of dropping the tank but that seemed to work out ok. Side note....I got the fuel pump for $75 plus the strainer $7 ( a lot for a pump )

That is cheap for a newer type fuel pump some run up to 500$ us or more.
The seal pops out and can be put in with a driver.
But Pinions bearings need the preload set.
Most of them will have a crush sleve in there.
Get some good repair info on it or here is a link that may help.
