will welding an installed axle fry the grease?

I shredded the the front driver's side LCA bracket last week and ordered the heavy duty replacements from Rusty's. Just wondering if those can be welded on without taking the front end apart. Do I need to make provisions to keep the axle cool while they're getting welded?
Thanks.

Weld it, there's no grease or oil in that area. Just use the right welder with enough amps so you get adequate penetration.

Other thing to remember that may be obvious but I'll say it anyway, keep your ground clamp close to your work. You don't want electricity arching across bearings and such


If your worried about the fluid just change it out. Inexpensive maintenance that should be done anyway. It's good to get in the habit of checking those fluids after wheeling trips to make sure they are not becoming contaminated, leading to more problems down the road.

just make sure to pull the control arm off so you don't burn the bushings

And disconnect the battery before welding on the vehicle!

That's an old wive's tale, there is no need to do that. There is no electrical reason why disconnecting the battery helps or protects anything while welding.

As long as the ground clamp is kept close to the work Jerry's right Electricity will take the path of least resistance and should not effect electrical systems if they are not between your ground and what your welding on.

True but even if the welder's ground connection were at the opposite end of the vehicle, which would be a very bad idea, disconnecting the battery would not provide any benefit there either. I disconnect my battery for various reasons but never just because I am welding something on my Jeep.

Thanks guys, I wish I had welding gear (and skills, but that's why you buy new gear, right?)
Taking it to a friend of a friend at a local frame and axle shop on monday, hopefully all goes well

When I welded on new brackets on my axle, I grounded to my ECU! *ducks*
