I can't get the rear 4 rear bolts off the driveshaft to replace it. I got one of them off with a lot of effort. I've been dousing them with PB Blaster. No help. I can't get my car high enough off the ground for a breaker bar. Two different Milwaukee 12V impact drivers are not budging them. I can get a good swing at them with a hammer, and if I damage the head of the bolt I'll never get them off.

Has anybody had luck with heat? Any other ideas? Maybe a better impact driver?

Appreciate any advice.

 

I have been down this road and know that an impact does not work well if at all, but a two foot torque wrench can take em off. I think there is too much slop when using an impact with the drive line moving. So you need to get its rear end up higher if you want to use a breaker bar. They are small bolts and only at about 110lb foot pound if I recall. With a breaker bar they come right off.

 

Thanks much for the reply. I don't see how I can get my car up high enough to use a breaker bar. I maybe should buy ramps rather than using jack stands? I block the rear wheels with wood to keep the shaft from moving, then move them and turn it when it I need to reposition it

My torgue wrench is shorter than my breaker bar. I'll try that tomorrow. Or worst case, a new impact with more torque.
