ls400 suspension diagram

[Lexbubba]

Does anyone have a shop manual with the front and rear suspension diagrams for a 95 ls400?

Wal*Mart has Chiltons. Well, mine does..your local bookstore would too.
It's a good thing to have, it's already come in handy for me.

I have the real factory service manuals for the ucf10/11, how much do they differ?

[Lexbubba]

Being that the shocks/springs are the same i'm guessing they are the same or very similar.

[Lexbubba]

Any help would be appricated. I'm trying to get some custom rear arms made to fit some wheels.

It'd be nice to see what angle those uca mount to the subframe at... knowing that can go a long way towards determining the best adj uca solution
Also, can someone confirm parts interchangability between ucf10 and ucf20? I assume ucf30 is totally different...? What other lexus models used the same rear susp as the ucfs10/20s?

[Lexbubba]

I'm going yo yank the wheels off this weekend and get some pics of the actual parts.

[One Ton VIP]

any luck on the pics and/or rear suspension subframe diagrams?

[Lexbubba]

None as of yet im getting ahold of some rear arms im going to cut/reweld for now. In a week I will be doing my suspension and will get some pics then.

I looked through my FSM's and there arn't any good pics of the rear or front suspension, they're all spread apart by component and you can't see the whole thing together. I'll do some more looking tonight, I might have just missed them.

[One Ton VIP]

what year is your LS? I think it's safe to assume susp was same between UCF10 and 11... and possibly even UCF20-21? I'm beginning to also believe that the first-gen GS300s and SC300/400s all used similar susp... but it'd be cool if someone could confirm.

[Lexbubba]

Ill try to compare with my friend's ucf10 if the ucf 20 is the same. I'm pretty sure it is.

[UTA LS]

Mine is a 93. I was always under the impression that there were small differences between the 10/11 and 20/21 but it was mostly in the brakes/spindle if I remember correctly.

[EXE.UCF10]

I believe the only difference is that the front shocks are longer on the UCF 20/21 than the UCF 10/11, but they will still bolt up.

Hmmm, well main concern is whether the control arms are interchangable... especially the front and rear upper control arms.
Oh, and also whether the uca ball joints are available separately either from Toyota or a good aftermarket manufactuer like MOOG (which most likely would buy them from the OE manufacturer for Toyota anyway, so quality wouldn't be an issue)

[One Ton VIP]

Semi update: tried looking for some aftermarket upper control arm ball joints for front and rear... no luck yet. I'm starting to see why it's a PITA for people to replace their ball joints since it looks like your only option is to buy the whole assy including the control arm and bushings from the dealer... for lots of $$$. So an aftermarket uca looks like it really could benefit people who are just looking for a good alternative to the oem piece, esp if it's competitively-priced..

I've actually been considering making a set of offset bushing like Daizen offers for the SC and GS. It wouldn't be too hard to machine and I could have a prototype set done in about a week if someone would like to try them out? I just need the dimensions of the stock bushings. Maybe on my next day off I'll go down to the dealership and see if the parts guy is cool enough to let me look at some bushings.

I would test these myself but my car is still stock.

[Pagong]

That would be a great idea....

Thanks for doing all this research and work. :angel:

[UTA LS]

Not a problem. Want to be the one to try out those offset bushings? Looks like you need them the most out of any LS400 on here. I have about a foot of 65 durometer polyurethane (fairly soft) that I used for some bushings in mazda speed protege control arms. I could probably have a prototype set done by the end of next week if I can get my hands on some stock bushings to measure.

does anyone know if UCF30 stuff will swap into UCF20 and thus UCF10??
