    Being a retired mechanic by trade for 40+ years I still like seeing videos how other techs do things. You're never too old to pick up a few tricks. I have to say your videos are very professionally done and very well focused (great camera) ! Also appreciated are the footnotes on socket/wrench size and torque specs. The relaxing music and absence of dialogue are refreshing. You have gained a new fan to a guy who's not an easy sell! Thank you

    Brilliant video. Both pinch bolts snapped when I was replacing both lower control arms. about to give the air hammer tool a try! I was trying to wedge a chisel in between the pinch gap, but it has been fruitless. I hope this works. Brilliant video
    thanks for your time.

      Glad it helped. Good luck with the air hammer method. It's my favorite. They rattle right out. There are pullers and some other methods to remove them, but give never needed any other method. Those pinch bolts suck big time when they corrode. Hang in there!

    I just went thru this war with my 06 wrx limited , it was originally an illinois car, since I bought it we moved back to Arizona, let me tell you what I fought that rusty ball joint for 4 hrs . Just before I was headed out to pick up a used knuckle I was able to get it out . Got it all cleaned up lathered in anti seize got it back together with a through bolt and its good as new ! I'm very glad to find out it's common for them to be a rusty PITA ! Great video and im glad I found it !

    You're definitely right about the pinch bolts, they can be buggers to get out. I was surprised how easily the control arm let go of that ball joint. I usually apply anti sieze on the shank of the ball joint, helps tremendously. Great video!!

    • @EasyFixShaun

      @EasyFixShaun  4 года назад +1

      I’m pumped it helped you out so much! Awsome man. Yup those ball joints are in the target zone. You could get more life out of them. When they do go bad they don’t progress too quickly. So you could always just keep an eye on them every oil change. That’s wants I typically do with my Subbies. But since it’s in the target zone not a bad idea to replace.

    I finally got around to doing this today on my ‘01 Forester and the bolt joint stud was seized inside the transverse link hole. The ball joint came out of the big hole from the spindle up top but simply would not come out from the transverse link below.. I was finally able to remove the ball joint only after removing the whole transverse link from the car. If you have to do the same thing I did, remember to torque both bushing bolts (towards rear of the car) to the body which hold the transverse link to a whopping 180ft/lbs! The other bolt which attaches the transverse link to the bottom of the cross member (towards front of the car) gets torqued to 72ft/lbs.. Some simple repairs can get complicated. I’m glad it all worked out in the end. Phew..

    If only I had watched this video instead of the other ones first when I did this job I would have installed the new ball joint into the knuckle the same way. Would have saved so much time and screwing around. I installed it in the control arm first and then tried to get it up in the knuckle but damn it was such a tight fit I had to use a jack to press up on the control arm and turn the steering wheel back and forth until it dropped in place. Also every so often hamming down on the knuckle.

    Good video. No need to unbolt the axle end though. Easier to unbolt half the sway bar link. That allows the A arm to drop fully. I guess removing axle end will allow you to heat the ball joint bolt without melting the axle boot. Good job. I have used a ton of aftermarket balljoints. They all hold up nicely.

    • @EasyFixShaun
      @EasyFixShaun  2 года назад

    • @EasyFixShaun
      @EasyFixShaun  4 года назад +3

      You could do it with out removing the axle. Sometimes a boot or cv axle on the inside joint at the transmission can get pulled apart and messed up. The knuckle gets moved around a little bit while working. So I just move it out of my way. Either could work though. 😀

  • @spelunkerd
    @spelunkerd 3 года назад +1

    Nice to see the grade 10.9 bolt, and the antiseize, to help out the next guy. Outstanding video, I really like the music. Normally I don't like videos without dialogue, but you got it right with the captioning. Regarding your remark about the torque, I wish RUclips would bring back annotations, they were invaluable to authors who want to amend something. Only question I have is why you don't use that Astro tool. For thirty bucks I would have thought a pro wouldn't think twice, if only to reduce the chance of damage to the knuckle. Or, maybe use EricO's idea of a slide hammer and two nuts welded together, since you use a lift and have room below.

    • @EasyFixShaun
      @EasyFixShaun  3 года назад

      Thanks man! I agree. Annotations would be a nice feature to be able to use. I should use the proper puller. It’s faster for me to vibrate it out. It’s my flat rate tech roots that drives me to do things like that. I should have put that in there just so everyone knows it is available. I will fix that on the next video for sure. Thanks for the feedback man. I really appreciate it 😁

    Not arguing, but some of the torque specs seen here conflict with ones I've seen posted elsewhere (e.g. lug nuts 79 ft-lbs for steel wheels, 89 ft-lbs for aluminum wheels -- video suggests 66; ball joint nuts 25 ft-lbs -- video suggests 22 or 37). Always pays to double check!

    • @EasyFixShaun
      @EasyFixShaun  3 месяца назад +1

      Thanks for that I appreciate it immensely. "Check your specifications to be sure", accompanied all of those specs in the video. There are some differences in Subaru models, but I wanted to give some general ranges to get an idea of the process. The wheels have different torque specs depending on aluminum or steel wheels. The lower control arms also have different specs for stamped steel or aluminum lower control arms. Usually aluminum control arms are on WRX's 😃

    Is this the exact same procedure on a 2016 impreza wagon? I've done all these steps, and even removed the sway bar links, and the control arm has zero play whatsoever. Knuckle won't budge to pull out axle either. The stud end of the ball joint will not release from control arm because I can't get CA low enough to pop the stud out. The ball joint also will not pop out of the socket either. I lifted the drivers side and placed on jack stands at frame rail under driver side door, i've PB blastered for 4 days, used pickle forks to separate ball joint from knuckle, and I've hammered the hell out of the control arm near ball joint and this thing will not budge. Maine vehicle, but only 85k on the car and this is unnecessarily difficult. Any help is greatly appreciated

    • @EasyFixShaun
      @EasyFixShaun  Год назад +1

      Hey! Sorry for the delay. Should be exactly the same parts. It sounds like corrosion is the problem. Corrosion will make these extremely difficult. If your pinch bolt came out that is 99% of the battle usually, you just need to remove the ball joint from the knuckle socket now correct? If so there is a puller available on amazon. I put a link in the description. I like to use my air hammer and chisel to vibrate it out at that point. It is a somewhat advanced method. A puller from amazon would be easiest.

They have a tendency to break from being corroded badly inside the knuckle bore at the shoulder of the bolt, and also the threads. I will make another video on that and the best way to go about it when that happens.

    • @EasyFixShaun
      @EasyFixShaun  3 года назад +2

      The cv axle removal allows the knuckle to be moved around easier. It isn’t necessary for removal. It does make it easier for me to pull knuckle to the side with one hand, and air hammer with the other hand so the ball joint can fall out. I use a chisel bit and hammer on the joint only. Don’t hammer on the knuckle. Basically I hammer right between to the two. The hammer will rattle them apart and should follow the ball joint on its way out. 😀

      Fairly straight forward as long as there is no rust. If there is rust the pinch bolt can be a big problem and break off. Some people then replace the knuckle. Some drill out the old bolt and install a through bolt. This video is the ideal no rust replacement on how it should go, but watch out for rust. It changes everything on the repair 😃🔧

      Penetrating will never hurt! Most times it is not enough for these unfortunately if they rust like I see them for 10+ years in the rust belt. The rust jacking between the bolt and knuckle seals out penetration. Upon pinch bolt removal the bolt brakes. But..... I have seen miracles with rust penetrant. Do it everyday for a month and it may just help 😃

      @@EasyFixShaun I made it on both sides without breaking the pinch bolt. Lubed the bolts two weeks in advance, which may have made the difference. Used a breaker bar very carefully to feel if the bolt would turn or not.

      Great Job! These things are a special nasty horrible repair animal all of their own if rusted even a little tiny bit. All the problems are at the pinch bolt. The threads stick or the shaft of the bolt sticks or usually both. Then it breaks. If there's no rust, they are quite possibly one of the easiest and fastest lower ball joint repair on earth once you do a few of them. 😃
