The knuckle could be heli-coiled if the damage is not too bad. If the stripped threads are on the caliper, replace the caliper.
If the sensor is stripped you will have to replace it. If the fitting or hole it threads into is stripped it is likely you can make oversize threads and use a fitting called a bushing to repair it. Mind you I got desperate one night and epoxied one in. Its still working but if I ever have to change it I am toast.
You have a few options. I it is not stripped just replace the gasket. If the threads are stripped or cross threaded, you need to have it repaired at a welding shop. They can easily fix this problem. Purchase a new drain plug and seek out a good shop.
If the threads of the sensor are stripped, it must be replaced. When this happens, the threads on the exhaust are usually also damaged. These can be repaired by "chasing" them with the appropriately sized tap. Be sure to use high temp. anti-seize on the new sensor. Sensors should only be removed when the exhaust system is at operating temperature.
You might try to use krol as this oil can creep into the smallest cracks to help loosen the spark plug. http://www.kanolabs.com/ The next problem will be the threads probably will be stripped. Use a Time-Sert insert to repair the stripped threads. http://www.timesert.com/html/sparkplug.html http://www.timesert.com Good luck!
Threads are stripped or bearing is disintegrating.
No way to fix that - your tank is scrap.
Could be that the threads are stripped on the plug or the head where the plug is screwed in. Or maybe it's the wrong plug..
The threads are what make it work. As you will know if you have tried to use a screw with stripped threads, it is useless. That is because a screw is a simple machine built from an even simpler machine: the inclined plane. The threads are an inclined plane wound around the outside of the screw, and are what change the twisting motion into a lifting motion.
Re-tap the holes (cut new threades) Use the TIme-Sert thread repair system will repair the pan.http://www.timesert.com Use a oil drain valve to replace your oil drain plug in order to prevent the threads from being stripped. www.qwikvalve.com
oil drain plug woesIt would be possible that tightening a drain plug to much into a aluminum oil pan, would more likely strip the thread before cracking the pan. AnswerYes it could, and possibly strip out the threads of the oil pan itself. Honda Man's AnswerIt's very common for aluminum drain plug threads become stripped over time. The oil pan could be cracked if an over-sized drain plug is used in an attempt to remedy the problem of stripped threads. Forcing an over-sized drain plug can stress crack the aluminum pan because the plug may be too large for the hole. The best fix for a stripped out aluminum drain pan is to use the appropriate size Time-Sert kit - The 1415C DLT is for 14x1.5mm, a very common size for Chrysler and Honda products. The Timesert kit allows for a professional repair to be done that accepts the original size drain plug. Of course if the pan is actually cracked then it will need to be replaced.
sounds like you have stripped the threads, if so you need a " heli coil " thread repair..and follow directions. those threads will need to be repaired or retapped,and always start the threads on your spark plugs by hand and not with a wrench.
