Hi all.

I am replacing the cones, and have now come to a stop.

I am having trouble removing the upper arm as the shaft refuses to move so I can remove the upper arm.

 

I have removed the retaining plate and both nuts, the shaft will mot move

I have applied quite a lot of plus gas already

 

I have a feeling it may be seized?

 

Any suggestions?

 

thanks

Invest in plusgas or pb blaster and soak it, have a few brews, then try again. (can amazon prime both)

If radiators out you’ll be able to get a long extension to the pin to give it a tap to release it from being stuck too.

I never remove the plate just the two bolts then it all just slides out once the rear nut is loosened off. I press on the nut and unwind as I go so as to not damage the thread.

 

you may need up to waggle the arm if the shaft is worn.

This too is how I do them. With the plate firmly locked to the shaft, you can roll it back and forth to help get it moving. The plate also give me something to (lightly) lever against. It's probably the front Thrust Washer that's jammed in the Subframe.

Hi all.

Update.

I had to hammer out the thrust washer as it was stuck in

The shaft is well and truly stuck in the upper arm, it wont move from side to side.

I suspect its seized in

So I believe the only course of action is to use a reciprocating saw to cut the safu either size of the upper arm

Cutting out the shaft is a tiresome task and will possibly result in damaging the top arm.

I will detail a couple of other options for you. 

With the locating plate, the thick thrust washer and both nuts removed, replace the thin retaining plate with a thicker piece and refit the nut. If the shaft is siezed in the bearings it will not rotate. tighten the nut as to act as a puller, drawing the shaft until it buts up on the thick plate. Continue with this increasing the spacer thickness until things start to move freely.

Another option is to rebuild the arm and tighten all the nuts up.

From you picture you have access to the arm, remove the shocker pin release the top ball joint and fit a suitable piece of pipe over the arm. working up and down might promote a bit of movement, just like freeing off a stuck nut.

My last and final option, which may sound drastic to some, but one that has to be employed sometimes is to cut a hole in the vehicle floor giving access to the pin. The pin can be drifted out from inside the car and them a plate fitted and welded up.

Heating the arm around the areas where the bearings are might help in all of the above.

Thats my take on things.

With the Front Thrust Washer out of the way, you should be able to move the whole arm forward. Then, leave the rear thrust washer in place and cut the threaded stub off, I feel a Reciprocating Saw would be a good weapon of choice here, using the thrust washer to save the arm. You should then be able to remove the arm.

Another vote for reciprocating saw. It may just be rusted in place. Cut it off and get all replacement bits
