    front end rebuild

    I have some noises that drive me crazy on my 1987 Brougham
    I am planning this winter to replace springs, shocks and would like to advantage of the winter to do some front end work.
    I was thinking of replacing all bushings. But what else should I replace? What about strut bearings and other components like pitman arm, center link, etc...? I`d like to make a list and order my parts soon. I plan on going with Moog parts unless you think there are better options for the price. Since I am going with heavier springs an Bilstein shocks should I use firmer bushings?
    What would you recommend to replace?

    The car was not abused and not much mileage on it, about 80k miles but is a 1987 with original parts most probably.

    Re: front end rebuild

    I just replaced quite a bit of front end parts on my 91 Brougham. With 80k on yours I wouldn't be too concerned about A arm bushing replacement. The pitman arm is no longer available and most likely not worn out on yours. Mine has 140k on the P arm and it's still like new. Most likely worn parts would be tie rods,idler arm & center link. I would stick with Moog, they still make a good quality part. Your best bet would be take it to a good front end shop and have them inspect the front end parts before alignment. Why would you go with heavier springs and Bilstein shocks? It's a Cadillac,not a Corvette! I use Monroe shocks and they work just fine and have a lifetime warranty. I doubt your springs need replaced unless they are broken. Mine are just fine at 140k. I did replace the steering gear box on mine due to excess play in the wheel. You can only purchase those remanufactured. Also take a look at your stabilizer links on the end of the front sway bar.

    Pitman arm is a non wear item. It's the center link that wears out. I had that replaced on mine 10 years ago. It and the shocks have been the only parts that have worn out on mine.

    I would also say that you probably wont need new control arm bushings unless they are squeaking or you've hit the curb a time or two. Which springs are you going with? I think the Impala springs and Bilstein shocks are a great combo, lowers the ride and stiffens up them corners. I rock Bilsteins in the front only and love how it stays flat when turning.

    Re: front end rebuild

    Thanks for your answers.
    The reason I want to have heavier springs as well as Bilsteins is that I am tired of the car bottoming out at every 3 potholes. I have new stock shocks with springs that supposedly came from a towing package Caprice. I still find this combination too soft.
    I replaced the stabilizer links already. One of the was broken.

    I am surprised by your replies, I really thought that after 25 years even though the car has low mileage, the bushings would be shot.

    In that case I will most probably start with replacing the springs and shocks and see from there if there is any play. I might have not placed properly the springs in their seats also. Something I need to make sure I do next time.

    The shocks I plan to go with are the 1516/1517's which are the progressive ones. They should be better suited for the roads in my area.

    The springs I am not really decided yet but I want to go with higher rates than Impala SS ones.
    For the rear ones I will go to about 190 lbs/in which should be the same rate as towing package springs on our cars. If it is regular springs I am thinking Moog 8543 or 8223. If it is cargo coils I am thinking CC611
    For the front ones I initially wanted to go for springs that have 710 lbs/in but these might be too stiff for the roads I am driving on. I will probably go for somewhere around 550 lbs/in (Moog 5552)

    I want to have the same height as stock for the rear or maybe even a bit higher
