I just replaced left lca and sub-frame on a 2003 Tiburon. I got 8 hours in it but still have to bolt the rack and pinion onto the sub-frame probably two hours left to be complete.
Support the engine and transaxle from above using a support bar. Raise the vehicle on a hoist lift. Remove the front lower control arms and swaybar bushings from the subframe. Support the subframe with tall jackstands. Unbolt the engine and trans mounts from the subframe. Remove and clips or brackets for such things as oil coolers or wiring attached to the subframe. Remove the susbframe mounting bolts, then lower the subframe from the car. Reverse the procedure. Get a wheel alignment. Be sure to tell whoever is doing it that you replaced the subframe as this information is critical for the alignment to come out the way it should.
If you are speaking of the front mount, it is a transmission mount, and you must lower the subframe to R&R.
No but I'm also looking for a front subframe for my L series theses cars are terrible for them apparently.
If you are talking about the frame that holds the engine in to the body, Its easy. there is a bolt that runs up into the body at the bottom of the bushing. Simply remove it and the lower drops out on the bolt. The upper may need to be separated from the body and the subframe (engine cradle) with a pry bar enough to slide it out. Slide the new one in, put a new lower one on the bolt, then insert the bolt back into the mounting hole.
With great difficulty, u need to lower the front subframe and dependeing on the engine and gearbox fitted, you may need to raise the engine slightly.
It it a somewhat complicated procedure, as you must lower the subframe to get clearance between the engine and the front subframe to have room to work. Get the car in the air using a lift/jackstands/etc.Next, remove the long bolts that hold the motor mounts to the subframe (13mm). Use a Hoist or A-frame to securely suspend the engine so that it will not fall out of the engine compartment when you lower the subframe.You will need a Torx socket (E-18 sized) to unbolt the subframe from the car's body.You may need to unbolt some front suspension components (Upper control arm to Spindle nut; Air-Spring/Shock combo tobody nuts) to be able to lower the subframe.Place a jack under the subframe before you remove the bolts; you only need to lower the frame a few inches to have room to work.Be sure to use a NEW oil pan gasket when it's time to put everything back together. This is not a job one wants to have to do over again because of leaks.
four upper and four lower.
It would be best to lower the ball joints on a Hyundai Santa Fe.
Jack the car up and set it on jack stands . you will need 2 floor jacks to support the subframe , one on each side. After sub-frame has been secured with the 2 jacks,loosen the 4 bolts that hold the subframe to the unibody of the car,now with the help of a sharp minded assistant,carefully and sincronizedly lower the jacks slowly, enough to permit you the removal of the bushings. A little prayer and lots of W-D 40 will make your job a lot easier and faster.
You have to lower the whole subframe. 6 bolts and beware of brakelines
Rather than replacing just the ball joints, replace the whole arm as replacing just the ball will more than likely not work. Use ball joint remover tools to remove and replace.
you will need to have your car alinged.. removing the lower subframe changes the alingment
