H&R/AGX suspension installed...making noises...help???
Hi, I just installed my H&R/AGX today and my front right strut is making a banging noise when I go over a bump. I have everything torqued to the correct specs, but it is still making noises. Any help would be appreciated. Thanks.

If its any help, I've had that problem also when I got my AGX's installed w/ stock springs. Umm...be sure everything is tight. something still might be loose, because I let the mechanic who installed mine the first time know...and he tighted them up (don't know exactly what was loose) within a few minutes of putting the car on the lift.

yes...it is a loud banging noise. Everything is bolted tight. here are the torques I used...
Strut mounts (3 top nuts) 30 - 40 Ft/Lbs
Piston nut (center nut) 50 Ft/Lbs
Strut lower mounting bolts 100 - 120 Ft/Lbs (with car still jacked up)

It may be your spring, did you wrap it in wire wrap?? I recommend doing that it lessens the noise.

The bumps were small bumps in the road, and it made loud banging noises...I didn't attempt to drive anywhere other than the parking lot...it's still at the shop right now.

Did u torque it when the car was still on jacks? Sometimes if you torque the car down right after the install it doesnt allow the parts to fully settle in. Try re-torqueing it and let us know.

Make sure the strut bearing isn't in upside down.
Make sure the upper spring perch is clocked correctly. The word OUT should face out or in line with the lower mount on the strut.

did H&R install two days ago
no noises here, but make sure the word out is lined up with the strut
also suggest dialing your AGX to their top (stiff) settings
otherwise you will be very dissapointed with the ride.
went from Sprints and KYB AGX set at 1 at the front and 2 rear
to H&R set at 4 at the front to 7 at the rear.
njmaxseltd - your suspension knowledge is very apperciated here,
but have one question concerning your KYB AGX settings
what settings you recomend with H&R ?
took me over 230 miles to figure out that H&R's need the stiffest setting from KYB AGX.
Thanks

I just received my H&R springs on Friday, and I will be receiving my KYB/AGX's this week along with a few suspension replacement parts. I searched the forums checking to see what I needed and many people kept referring people with questions or noise problems to one thread, this one:
Part #s for OEM Nissan Recommend Suspension Replacement Parts
Many have been asking about the part #s for the OEM isolation sleeves for which I used on my H&Rs to eliminate any chances of noise coming from my suspension. Install was done at Maximum Tuning (516)676-8470. Installed were new KYB AGXs, H&Rs, ES FSB Bushings. Replaced were FSB endlinks (def. check on these when you do your suspension, thanks to Jeff noticing, my passenger side endlink was completely broken off, prob due to NYC pothole, supposedly common problem of them breaking on the Maximas). I wouldn't recommend any other shop to do the install, I'm even getting my friend with a 525i to get his suspension done there.
*highly recommend
The following parts were bought from Koeppel Nissan in Queens:
2 - *Strut Bearings (54325-5V000) - 27.16 each
2 - *Front Dust Boots, includes the bumpstops (54050-38U02) - 12.11 each
2 - *Rear Dust Boots, includes the bumpstops (55240-0M315) - 23.76 each
2 - Front Rubber Seats (54034-31U01) - 10.40 each
The FSB endlinks that were bought to replace the broken ones were bought at Baron Nissan by Jeff's shop
2 - FSB Endlinks (54618-0E000) - 10.84 each
The remaining parts were ordered from Courtesy Nissan
2 - *Front Spring Polyurethane Isolation Sleeves(top) (54034 - 31U01) - 9.17 each
4 - *Front Spring Polyurethane Isolation Sleeves(bottom, 2 on each spring) (54034 - 31U20) - 9.19 each
2 - Rear Rubber Seat (55034 - 31U00) - 8.16 each
2 - Front Orange Spacer (54329 - 39U00) - 7.22 each
2 - Rear Bushings (56218 - 61L10) - 1.81 each
4 - *ES FSB Endlink Bushings (4803G) - 2.73 each
To anyone upgrading their suspension, I highly recommend the items with an *, in my case I have a 98 with ~60K driven in NYC and I just felt that I should replace any wear items. I want to do my suspension right the first time and not worry about noise down the road, pretty much I don't want to have to mess with my suspension ever again. For the isolation sleeves, I def recommend this as a must. I've seen the wire loom recommended by people on the org and it just doesn't compare with the OEM Nissan ones. The Nissan ones are just thicker and go on with a self adhesive on the inside of the polyurethane tubing. Since the install 2 weeks ago, my car is dead quiet, just the hum of my catback, plus I've taken the setup through the best NYC has to offer, not one squeak. Def also get new bushings for the FSB if not the ES ones, when my old ones were taken out, they were compressed to a 1/3 of their original size.
END OF THREAD
I ordered the parts that were highly recommended as well as the FSB bushings, and the rear isolation sleeves for the springs(one for each spring). I did not have the # for the rear sleeves but Kaleb at Courtesy Nissan helped me out with this. It all came out to $214.xx not cheap, but my car already has 100k on it and is probably due for a few of these parts. Besides my local dealer wanted almost $400 dollars for all these parts, so I don't feel so bad. I just don't want a noisy suspension. Maybe you did all this already, but if not let me know if you are interested in the prices for the items that I bought.

i just got home from installing agx/h&r's. myself and ethan (emax02) did them, and when we were taking them off we lost the order of all the part on the shocks, and we forgot if the bushing went on top, or bottom. so we later realized it went on top but if we to leave it on the bottom it would make a loud banging noise quite similar to what you discribed. are you sure that you put everything back together corectly?? we took our time and did the project, and i have no complaints, or noises... double check everything. goodluck.

The noise might be caused by the strut bearing not sitting correctly...
