d.p Posted August 1, 2017 Report Share Posted August 1, 2017 Anyone bought them recently? If so from where? Mine are tired and in need of replacement. Seen the thailand ones on the bay but wondering if there is anything else out there. Quote Link to comment
Draker Posted August 1, 2017 Report Share Posted August 1, 2017 Just get the thai ones. They aren't exposed to direct sunlight and are cheap. Buy two sets. Quote Link to comment
Crashtd420 Posted August 1, 2017 Report Share Posted August 1, 2017 You mean those 4 little rubbers that attach to the fenders under the hood...? I just bought those eBay ones myself... seem just fine for what they do. 1 Quote Link to comment
d.p Posted August 31, 2017 Author Report Share Posted August 31, 2017 I have a 521 and the hood latches tight, the hood bumpers are little worn/flattened but anyways at speed on the freeway (60+) the hood flutters and shakes. When the hood is closed I can still push it down like an 1/2 - 1". I guess that is because the spring has room to travel. Is that normal? And could that be why the hood shakes? Quote Link to comment
Draker Posted August 31, 2017 Report Share Posted August 31, 2017 The hood is boned to the frame with panel bonding agent. hood flutter is probably worn hood bumpers. I replaced mine on my 510 with OEM units and it still does it. You can get height adjustable bumpers and install those on the core support and that should fix it. 1 Quote Link to comment
Crashtd420 Posted August 31, 2017 Report Share Posted August 31, 2017 I think i know what you mean.... The skin vs frame. That makes sense My hood was like that.... I was told to use seam sealer.... Mine was all dryed and breaking apart.... I think I have a pic some where..... Quote Link to comment
Crashtd420 Posted August 31, 2017 Report Share Posted August 31, 2017 Did you post this somewhere else.... I swear you mentioned something about the skin and the frame work being unbonded.. Quote Link to comment
Crashtd420 Posted August 31, 2017 Report Share Posted August 31, 2017 I guess the real question is where are you seeing this flutter.... Is it the center of the hood fluttering like a sail... Or side to side because the bumpers are worn..... I always thought the front lock was pretty fixed where it was, with no adjustment.. Quote Link to comment
banzai510(hainz) Posted August 31, 2017 Report Share Posted August 31, 2017 my hood side bumpers were worn so I built them back up with soem black permatex RTV. I had a 510 with a rotton hood and the braces where the panel bonding agaent broke or wore out whcy caused a flutter and the latch area was rusted out on hood. (Lucky it didnt fly open on me) 1 Quote Link to comment
d.p Posted August 31, 2017 Author Report Share Posted August 31, 2017 It bounces on the edges. Moreso on the passenger side. Hood just has a lot of up and down movement when latched shut which I don't think it should.And my bumpers are tires as shit. So I doubt they are holding the hood that well if that is what they do.video: https://flic.kr/p/X21rU3 Quote Link to comment
banzai510(hainz) Posted August 31, 2017 Report Share Posted August 31, 2017 winging this here but look lik the hood can come down more. Open the hoof and on the bulb shaped plunger with the spring youll see a screw driver slot you can tun this in and it will pull the hood farther down or up to get it prefect. just mack sure the female part on the core support fully encloses the bulb to its seculy latched. as for the side wiggling Like I sad I just got some Black RTV and build up the old hood bumber pads. leave hood open over night and bam close hood . it will fit better over time if you put too much on Quote Link to comment
d.p Posted August 31, 2017 Author Report Share Posted August 31, 2017 weird cause its pretty well lined up with the fenders...for the most part. If it came down more it would sit lower than the fender lines. Will play with the plunger a little bit and see what happens. Do the bumpers help keep it in place/stable? I am going to replace those fuckers anyway. Quote Link to comment
5t341tH Posted August 31, 2017 Report Share Posted August 31, 2017 Those bumpers definitely help. I had old, rotted ones and replaced them with new. Now the hood is straight and wiggle free. Now I just have to deal with the hood being separate from the spine underneath somehow... 1 Quote Link to comment

Now I just have to deal with the hood being separate from the spine underneath somehow...Use seam sealer. That's what I was told to use... if you look you ll see the dried up globs between the hood skin and the spine structure... just grind it out and redo or add more next to it.... depends on how perfect you want it ... And DP the front line of the hood seems crooked.... high on the passenger and a little low on driverside..... Maybe it is just those 4 rubber things... Try using some tape or something to build up the driver side rubber and see if it makes it look straighter. 1 Quote Link to comment
d.p Posted August 31, 2017 Author Report Share Posted August 31, 2017 Same problem with my seams as well. Yeah its not equal on both ends so I am going to order new bumpers and go from there. Quote Link to comment
d.p Posted August 31, 2017 Author Report Share Posted August 31, 2017 Well I tried to switch the driver side bumper with the passenger but the driver side disintegrated when I pulled it out. So I put the pass on the driver side and even without the passenger side one the hood was tighter than it ever was before. So I went and ordered 4 bumpers from the dealer ( 65158A4500). Also the plunger is seized so I couldn't adjust it but don't need to. Quote Link to comment
datzenmike Posted September 1, 2017 Report Share Posted September 1, 2017 Get suitable size hose, about a inch long and screw it onto the ledge. Hood will close and crush into shape. Go to wrecking yard and find a set of these and mount on the top of rad support... Quote Link to comment
datzenmike Posted September 1, 2017 Report Share Posted September 1, 2017 Why do we have two posts on this??? http://community.ratsun.net/topic/72433-hood-bumpers/ Quote Link to comment
d.p Posted September 1, 2017 Author Report Share Posted September 1, 2017 Like rubber vaccum hose? Screw that down? And WTF are those? What would I even be looking for in a wrecking yard to find them? Ordered 4 hood bumpers from the Nissan dealer today. $12. Hopefully they work otherwise $50 from Thailand. Quote Link to comment
d.p Posted September 1, 2017 Author Report Share Posted September 1, 2017 Can you merge please? Thanks boss. Quote Link to comment
wayno Posted September 1, 2017 Report Share Posted September 1, 2017 I put a short piece of soft heater core hose on the passenger side around 6 inches back from the front, one cannot see it and the hood quit wiggling around. I have both the Nissan and Thai types, just been to lazy to make the effort to install them. Quote Link to comment
DanielC Posted September 1, 2017 Report Share Posted September 1, 2017 There are actually two different types of hood bumpers on a 521. i was able to get the rear ones at a Nissan dealer a few years ago, but the front ones were NLA. The post (or pin) that goes down into the hood latch on the core support has a lock nut above the plate that bolts to the hood. You loosen the lock nut, then you can adjust the height of the closed hood with the screwdriver slot in the catch pin. 1 Quote Link to comment
datzenmike Posted September 1, 2017 Report Share Posted September 1, 2017 Balanced tires, good steering ball joints, idler arm and good kingpins will also reduce shaking. Quote Link to comment
