I replaced the rear struts this past weekend and did the attached write-up. I hope others will find it useful.

^^ FYI there is nothing attached to this right now....

Thanks, I just realized that. I am having difficulty getting the PDF to upload.

Here is a write up that I did when I replaced the rear struts on my 1991 LS400. The job was pretty straight forward and took about two hours. I used KYB GR2 and found their ride to be noticably firmer than factory struts. It would be interesting to compare other brands to see which ones are most similar in ride to the originals. Regardless, I am happy with the much improved handling over the worn out struts that I replaced.

Good info - thanks for writing it up for us. I'm about to do this job on my '91. On the rear, in addition to the KYB GR-2 struts, I'm planning to replace the strut mounts and upper insulators, but not replace the lower insulators and bumpers, since they look OK.

Did you replace any of those parts when you did this? Doing the fronts any time soon?

rears are sooo easy.

Did you forget to put the rubber between the spring and the strut on the lower end of the spring?

KMinAF

No I didn't forget, it just didn't get mentioned in the write-up.

Thanks for the write-up

Just wanted to add I followed it but realized removing the lower sway bar joint nut may not be necessary.

Also, removing the first one took us nearly 3 hours, the second was 5-10 minutes. Problem was we thought the strut should come UP so the bottom of the strut cleared the control arm then out. Kinda dumb but once we tried lowering the strut and aiming the bottom down and into the underside of the car so the top of the strut could come out and clear the fender we were in business! LOL

- that obvious point wasn't clearly explained in the write-up.

KMinAF

Sorry it wasn't clear enough, the part where I said to lift up on the lower control assy related to what you are saying. I too spent the better part of an hour trying to figure out what turned out to be so obvious.

Nice write up. I am getting close to doing mine. Just one question does an alignment need to be done again if only the rears are changed?

KMinAF

Changing the struts usually does not change the suspensions geometry therefore an alignment is not required. However, if an alignment has not been done for some time I would certainly suggest a four wheel alignment by a reputable service center.

lol oh really, if you replace the SHOCKS when they're worn you will see a measurable difference in height, which very much changes the suspension geometry and WILL require a realignment.

unless you feel like changing your perfectly good shocks for another set of perfectly good shocks, and end up with the exact same ride height...
