I am attempting to replace both rear axle half shafts... 2007 is250... stock. 220,000 miles. I am unable to remove these bolts on either side. They won't budge and there is very little room to get any leverage. I have hit them with lage quantities of PB blaster.

Would appreciate any suggestions.

Thanks

Jim

 

Have you tried breaking it loose with a hammer or 5 lbs sledgehammer? Sometimes a little sledge hammer can work magic in tight spots to break loose the stubborn bolt. Another thing is to add a little heat with a small torch.

 

Heat and a larger breaker bar should do the trick.

 

Impact wrench.

 

Heat it up and impact gun

 

Where was your car driven at the majority of its life on the road? Did it spend a considerable amount of time on salt roads?

 

My is350 was winter driven and my mechanic had to cut the bolts out and replace with new there only 3$ a piece

 

I don't see the heads of the bolt/nut being rounded off just yet. I'd hit it with a torch and the longest breaker bar you can get your hands on. Should be enough to do the trick.

 

I beat the crap out of it, no movement. Heat was a problem because of the rubber bushing. I removed the heat after smelling rubber burning. Impact wrench on the bolt did nothing. I ended up cutting it on one side and grinding down the head on the other. Then, I drilled through the bolt. More beating and it finally came out.

 

WOW! You went to the last resort fix; but glad you finally got it out.
