Getting ready to tackle my lower control arm bushings, got new bushings (duh), brackets and what I thought were the right bolts, but apparently I only got half the bolts right. New brackets along with the new washers and nuts to cap the bushing, however I realized the bolts I thought I correctly ordered only fit on one side and are too small on the other. Once under the car I realized I needed this bigger bolt, however, scanning over the front axle arm/steering knuckle I cannot find this bolt listed on it
Smaller bolt (90105-12332) which is used on the other side. The moment I got the new brackets and placed the new bolt in them I realized I needed this bolt, but the front steering knuckle diagram does not list this big bolt?!?!
This bolt faces outwards from the car, bigger than the other side bolt, I've read this bolt torqued to 100 - 101 ft lbs, meanwhile the smaller bolt (90105-12332) is torqued to 44 ft lbs
The front lower control arm big bushing bracket has 2 bolts holding it one big one that takes 22mm secret to take it out and one small one thay takes 17mm socket to take it out what is the thread pitch of the small so I can retap hole not finding this info has me ready to blow my brains out
What kind of issue do you have? You don't usually need a tap to replace the control arm, only if the thread is wrecked for one reason or another. Any bolt you find on sale follows specific standards, for Toyota, any bolt with a 17mm head will likely have an M12x1.25 thread, 12mm on the outside diameter, with 1.25mm between each pitch of a thread. To make sure, measure the outside diameter of a bolt, which will give you the first value, and then use a thread gauge like this one to get a second value.
Then again, make sure that you absolutely need to use a tap in there before you commit, the threads in cars are usually rolled in, meaning that instead of being cut, they are forced into the metal, making them a lot stronger, using a tap will cut those threads, making them softer for no apparent gain. If the thread is just dirty, use a thread chaser that won't damage the thread's properties, while doing the job just as well.
Hope this helps and best of luck!
