My 01 park with 48,000 miles. I have just replaced the front struts with monroes and new strut plates/bearings, and the problem started. I have changed out the right side twice. Problem I have is a poping noise coming from the strut tower in the upper area. It makes noise while driving straight, it does not make the noise when turning left or right. Poping noise is relative to the road and the bumps. The poping noise sounds like popcorn poping. Yes front end is tight and properly alined at a good shop. Any ideas what the poping noise is...left side does not make the noise. Bad strut? problem with both right side upper mounts and bearings? bad control arm bushing with the noise traveling? Any advice would be helpful...anybody have a problem similar on another make of car? Thanks.

Welcome to AF.

I see you replaced the upper strut mount/load bearing but it isn't clear on which brand was used. Other GM car owners like "W" body Regals and Grand Prixs have experienced or complained about problems with Monroe struts and Monroe upper strut mount/load bearings causing a popping sound under acceleration or a creaking sound during other driving conditions. I recall one remedy was the owner went back to the OEM/GM struts and/or strut mounts.

Well I have done some more digging, seems to be a problem with the strut mounts from monroe are thicker than oem. I will try part # 22181835, they say this part is thinner on the outside dia. I will try the dealer for a replacement. Yes I replaced with monroe products, struts, bearings and mounts. I suppose the original mounts are long gone aka refuse truck!...This is getting to be a expensive lesson! Thanks, for the confirmation bnaylor. I will update my progress as I move along with this.

You're welcome. Yup, I've heard that comment before $$$. :lol:

It sounds like you are on the right track. :thumbsup: Too bad the old strut mounts were discarded. Although they have been known to go bad early in life generally they last well beyond 100K+ miles. All I do is clean them up, inspect the rubber cushions and specifically the load bearing then lubricate with waterproof silicone grease like Belray brand. Not all parts are created equally such as OEM versus aftermarket.

Good luck and please keep us posted on the outcome.

Well bought the strut plates from the dealer...make sure you get a loan to purchase! Yes they were in stock, like the dealer knows what is going on. Changed out only the right side. At first no popping, but after 100 miles slight popping. Boy I can not fiqure out whats going on. I wonder if the plate is flexing? It looks like the strut rod coming into the plate is sloppy. I am going to try to double washer the top end maybe that will tighten it up, as it seems to pop because of said slop. It is a little bit warmer today, I will see tommorrow as the car sits overnight and the temps drop. But the popping noise now is at least tolerable, it does not resonate through the passenger compartment. If it does not get worse I will probably live with it. At this point I see no way around going to the dealer to get this done next time. The dealer would probably deny hearing any popping noise after they replace all the parts! At least my loan for the plates will be paid for by then!!! LOL I have wonder why no other posts about this problem???

None in PA that I know of but here is one we just got at Grand Prix concerning Monroe struts. Just annecdotal info and probably nothing to help you resolve the issue short of going back the the OEM/GM struts.

Well more updates. In cold weather, no noise at all. In warmer weather very slight noise. At this point I am going to live with it, as you can barely hear it. Strut plate OEM did take care of most noise, strut plate was 150.00 at dealer. The bushing 22181835 is 15.00. I am not putting the the bushing part in at this time. The monroe strut/mounting kit package aftermarket....verses oem is the oem plate with the three mounting bolts, the bolt holes?? are shorter on the oem and longer on the aftermarket. Which on aftermarket causes the bearing to ride on the aftermarket bolt holes. The oem holes are appox 1/8th inch shorter then providing enough clearance for the bearing and the assembly to turn freely. Maybe at a later date I will install 2218135. The noise is now not very loud and you really need to listen for the noise as it happens only as you start rolling or coming to a stop. So my therory is this....OEM strut plates, after market struts, bearings and related material, you can use aftermarket and then at that point I would install the 22181835 part on both sides. Just a fyi the drivers side did not make any noise at all through this whole process, along with all the aftermarket parts with no rubbing on that side. I do not understand it fully but....I hope this helps someone in their quest to save some money and some aggravation.
