RemSteele Posted October 17, 2020 Share Posted October 17, 2020 Hi team, Just picked up a well maintained 91 115k. A knocking noise like front struts, at the very least strut mounts. Are these parts available? Any special tools/knowledge needed to replace the front struts. I have very good mechanic but primary cars serviced are BMW 's. Thanks for your help, RJ Link to comment Share on other sites More sharing options...
Ronnie Posted October 18, 2020 Share Posted October 18, 2020 Parts are available. Instructions for replacing are here on ROJ. Probably need to replace all at 115k. Link to comment Share on other sites More sharing options...
DAVES89 Posted October 18, 2020 Share Posted October 18, 2020 (edited) I find that if you need struts, you should also need the strut mounts. Don't know if you plan on keeping your car long but if you do, buy Monroes. They have a life time warranty and you will get free replacement if they fail. I have a shop install them and then keep the receipt for the warranty. Edited October 19, 2020 by DAVES89 Link to comment Share on other sites More sharing options...
89 MAUI Posted October 19, 2020 Share Posted October 19, 2020 Be prepared if you are changing out the rear struts. My '89 was a northern car and saw salt highways. When I went to replace the rear struts I found the upper mount of the strut tower had rusted the "D" mount hole had rusted into a circular hole and too large to mount the strut to. I removed the rear suspension from the Reatta, there is only 4 bolts that mount the rear suspension to the frame, and I took the rear suspension to a welders shop and they welded in a heavier plate to the upper strut tower and cut in a mounting hole for the strut. I also had the welders shop do the other shock tower, it cost me $125 but it strengthened the rear suspension. Also be aware that when you go to remove the lower strut mount be careful not to damage the mounting rubber cushion, this rubber cushion is not available anywhere for replacement. Left Image is of rusted strut tower - Right Image is of repaired strut tower. Good Luck Woody 4 Link to comment Share on other sites More sharing options...
RemSteele Posted June 15, 2021 Topic Author Share Posted June 15, 2021 Hi Team, I need your help. Having my mechanic do the front struts and the mounts. Replaced with after market mounts and after installation very quit on smooth roads but a loud banging/knocking when you hit bumps. After taking it apart and comparing to the original a difference in mount bushing size (I think) see attached was notice. He suggesting OEM from GM at almost $300 each. Do I have any options?

Padgett Posted June 15, 2021 Share Posted June 15, 2021 Last time I did one, the front mount had a bearing with a few balls in it at the top of the mount so the strut could steer. Suspect it was called the strut mount bearing. Link to comment Share on other sites More sharing options...
RemSteele Posted June 16, 2021 Topic Author Share Posted June 16, 2021 Thanks for your response. Not sure I understand, but he indicated a measurable difference in the OEM strut mount and the aftermarket (2 different manufacturers) RJ Link to comment Share on other sites More sharing options...
2seater Posted June 16, 2021 Share Posted June 16, 2021 I don't remember there being any issue with using new strut mounts with Monroe struts? Are you sure the knocking noise isn't contact between the anti-sway bar and the front subframe? This is not uncommon when the bushings wear out where they mount under the cradle and have done two of them personally. Link to comment Share on other sites More sharing options...
