One last question - for now...

As part of this work, I am reading through the Bentley manual. In the section on replacing the front spring, it tells the mechanic to remove the trunnion before taking the spring pan off. I do not see why this is needed? My spring came out with the trunnion still installed.

I will take the trunnion off for a rebuild too, but I am just trying to understand things better.

As usual, thanks in advance,

Not sure why you need to rebuild the trunnion but if the sleeve is frozen your going to have to soak it for days unless you want to buy a new one all I can say from experience is that if you don't buy or make the proper spring compressor your not going to get it back in look it up on youtube

Ralph,

I have the spring compressor. It works like a charm.

Thanks for the feedback.

Big Chill --- I never found it necessary to use the spring compressor so long as the weight of the engine can keep the chassis from rising when the jack is used. The order in which to replacing a spring is the same as when you took it out, only in reverse. I do use a short block of 2x4 cut to fit up into the spring pan while compressing the spring with the floor jack during installation. If you are not comfortable unless a spring compressor is used, then by all means...

If your objective is to remove the spring pan, I would remove the upper ball joint (two bolts through control arms) while supporting the spring pan and remove the trunnion assembly so the entire vertical link is out of the way. Removing the pan is possible without the above procedure, just much more difficult. I would remove the vertical link/trunnion prior to removing the spring, just for access.

A bit more information.

I am dis-assembling the entire front end. It is all 30+ years old. I MUST replace the rear inner lower A arm bracket, so all bushing and hardware are being replaced. I have not done this kind of work in a long time, but I have done it. I used to use a jack, but prefer the spring compressor, which I have.

I was just really curious as to why Bentley wanted the mechanic to take the trunnion apart when replacing the spring....

Thanks for the support and advice, as usual.

You definitely don't need to do anything to the trunnion in order to drop the spring pan (I just did it last spring). Not sure why Bentley states this.

I replaced the front springs and shocks a few weeks ago. I just removed the spring pan. Not sure why one would to remove the trunnions and/or ball joints...unnecessary work for nothing. Used the tool from Moss.

Regarding dropping the trunnion - that is what I thought, just wanted to be sure I was not missing something.

Be well, everyone,
