Bolts on rear tires won't loosen on 98 E320
Hello
Just bought this car on Monday for my daughter. I am trying to rotate tires but I can't loosen 2 bolts on r rear and 3 bolts on L rear tires, one of them snaped. I'm of fraid to go on they might snap sprayed wd40 on them it's like there frozen even whith a pipe to put more force. Is there another option of taking them out? If I loosen the axle nut and brake line whil it come out? That way I can drill them out. 98 E320 thanks, |

Well. I think you will have to bite the bullet. You might have a little better chance to get them out unbroken if you would take it to a shop that would remove them with an impact wrench. That rattle of the impact will loosen them usually without breaking them. Spraying with a penetrating oil might help, but it is difficult to get the oil in there. Use a torque wrench when putting them on at about 70 psi and they might come out easier in the future.

You are just going to have to get a bigger impact wrench and possibly more power, (air pressure). It will take them out!

That won't help much with the broken one. You may end up needing a new rim for that.
If you have any of those bolts left when you're done, THROW THEM AWAY. They are deprecated. The new bolts have a shorter shank, and do not break as easily. |

Testing shows
The "Best" penetrating lube is a mixture of ATF and Acetone.
(Do not breath or get it on your skin,in your eyes!) I'd treat the lug bolts with that (let soak overnight) and then when you're ready to try the "release" ,tighten the bolt [clockwise] @ about 100ft lbs a "Hair" [You're just trying to set them up to "break free",upon counterclockwise pressure] then try loosening.

Might have to heat them with a torch! To save the rim put a long socket on it and heat the crap out of the socket from the side trying not to heat the rim, get a piece of wood or metal hole saw it and use it as sheild from the heat! Soak the wood in water if using wood. Or drill them out!!!

Also when using heat/torch use liquid wrench or another non flamable stuff

Since it's a 98, you probably have the long bolts, something like 3.5 inches? They flex/twist when you use an impact wrench and won't loosen. You have to use the old fashioned method, a long breaker, put a pipe on it if you have to. But do try to tighten them just a smidge first. For those that have been on the car a long time, and that you used the impact without result, they may have cracked and will likely break. Before I discovered this fault, I broke three of them and had to drill them out.
MB issued a new bolt to replace these that is shorter and doesn't flex. I like the way mine look and have kept them, but taking note to inform any shop that manual removal is required. If they use an impact wrench - they pay for the repair.

Thanks to everyone for the replies.The car had new tires who mounted must of used the impact very tight all weels. 5 wouldn't loosen, tried all the methods mentioned, 4 broke had to drill them out past the flange for the tire to come out, after the tire came out the remaining part loosened by hand, the front ones were replaced to shorter ones, I'll order new ones for the rear (shorter ones). Damaged one of the rims a bit on the countersink. I'll try to countersink the holes at work (Cnc operator) if not I'll swap with spare tire.
Thanks to everyone |
