Hi everyone, I am new to this forum group.
I am currently working on a 91 LS-400 that needs both of the front upper control arms replaced. I can not find a repair manual, for a reasonable price, any where. Could some one direct me to a site that has the info? I looked at the "AARC" site, and it starts out with the 93-94 LS-400's. Or maybe some one could just explain the disassembly and reassembly procedure?

Than You

The repair preocedure for the 93-94 LS is still the same for the 91. Here is a site which will be very helpful to you in the restoration of the LS you are working on.

its pretty straight forward...any weekend mechanic can do it easily...just gotta have the right set of tools...

 

Wow, I was making this more complex than I had to. I did run into problems though. All my fault though. I loosened the nut on the top of the spring a little too much, and it decided to pop off. All I had to do is throw my spring compressor onto it and tighten it down. But that's not what I did. I removed the lower control arm, steering knuckle, and sway bar connection. Next the rotor hit the ground and the spring and shock just slid out. A very hard way of doing it. Needless to say, the other side went much smoother.

By the way, I bought my upper control arms from Ebay for $200 for the set, from what I was finding everywhere else, that is a great deal.

Thanx,
