Anyone know what the going rate is to replace a rear main seal in a 5.3 LS? 4x4 with automatic

I don’t know warranty time but it’s a chore being 4x4

Depending on year model 5.5-7ish hours. Make sure they replace the oil puck pickup tube seal while the oil pan is off. known issue for causing air in the oil supply takes about 2 mins longer to put this on. The pickup tube can cause a Noticeable lifter tick at times. Usually upon start up. The rear main has a housing gasket as well. Make sure it is replaced at the same time while they are in there. I would make 100% sure it is indeed the rear main seal. A lot of the time it is just the pan gasket. I always replace the two seals on the exhaust pipe flange while the exhaust is out. Also, there is a dust boot on the front drive shaft and I see guys not putting the clamp back on. Not a horrible thing, but some engineer was paid a million $$ to say it needed it. I don't always agree with engineers but in some cases I do.. Hope this helps.

Do you have to pull the oil pan to replace a one piece seal? I have not been in a modern engine, so i honestly don't know. Does a 5.3 ls have a one piece seal?

It’s definitely the rear main. I’m a pretty good mechanic and an engineer. I can fix it but don’t really want to. Just fishing to see how far my “don’t want to” will go. It’s my son’s vehicle.

In that case. Do it. Cheaper for you and your son to learn. And not that bad. Book time vs real time. Real time 4-5ish hrs
