GTLEGACY007 Posted November 1, 2010 Share Posted November 1, 2010 So I just my aging, cracked, stock LCA bushings replaced with new Perrin bushings. I had been having some front suspension issues, which this resolved. The front end feels must more planted now, and hugs the road just as i'd like. HOWEVER, ever since having these installed (literally as soon as I drove away from the shop) I noticed the ride is now very rough over even the smallest imperfection in the road. I can even feel the reflectors in the road between lanes when switching lanes. So my question for those who've replaced their LCA bushings with aftermarket bushings is, is this normal? Should this be something I should be concerned about? Anything I can do? It's really increased the ride harshness and just the overall noise in the cabin, which kind of makes the car feel cheap to me, as its very loud while on the freeway. Input?

cybonic Posted November 1, 2010 Share Posted November 1, 2010 i am on super pro lca caster bushing. yes it will add slight nvh. but it doesn't affect the comfort at all Link to comment Share on other sites More sharing options...
fonts Posted November 1, 2010 Share Posted November 1, 2010 I have no experience with the Perrin bushings ..... but have read reviews that indicated that they are more harsh than other brands. Link to comment Share on other sites More sharing options...
mustangendsley Posted November 1, 2010 Share Posted November 1, 2010 /\ dito. much harsher than anyother brand out there. Link to comment Share on other sites More sharing options...

If NVH and ride quality are important to you, the Perrin LCA replacement probably was not the best choice. You have replaced a soft rubber bushing with a Spherical bearing. This will have essentially NO give, and transmit any vibration or impact without any isolation like the stock bushing provides. Per Perrin's Website 'the PERRIN Performance PSRS replaces the front lower control arm mounts with a solid connection using a teflon lined spherical bearing.' AVO's LCA bushings would probably have been a better choice for you, given your concern. Its a poly bushing, so its much stiffer than the stock bushing, but it still has the ability to 'give' and absorb some impacts and vibrations (though not as much as the stock bushing would). __________________ ~Scott '05 Outback 2.5i Wagon Willow Green Opal/ Moss Green Metallic 225/60HR16 Bridgestone G009's Link to comment Share on other sites More sharing options...
PhillyWilly Posted November 1, 2010 Share Posted November 1, 2010 I went with Whiteline after reading harshness with Perrin. With Whiteline I barely noticed any increase in nvh and with much improved steering and handling. Has been one of my favorite mods. Link to comment Share on other sites More sharing options...
notthesnail Posted November 2, 2010 Share Posted November 2, 2010 If you decide to change them, I don't think they can be reused once they're pressed out. Try to find a buyer who will trade the entire LCA or buy a spare set. I'd offer mine, but I'm way far away in the salt belt. Link to comment Share on other sites More sharing options...
jfg22557 Posted November 6, 2010 Share Posted November 6, 2010 The perrin LCA PSRS kits can be pressed out and reused regardless of the fact that their solid. Picked up a used set myself a while back, however decided not to install them for the exact reason you guys are discussing. Replacing with either superpro or whiteline poly offset.

GTLEGACY007 Posted November 8, 2010 Author Share Posted November 8, 2010 We'll, guess I should've done a bit more research on these before I pulled the trigger. They're livable, I mainly just wanted to be sure there wasn't some problem with the install. I think i'll stick with them, maybe if I get really tired of them some day i'll replace them with AVO or Whiteline units. Thanks for all the input!

usedtobeaJusty Posted November 16, 2010 Share Posted November 16, 2010 How hard is it to replace the LCA bushings? Do the LCA's have to come completely off the car? Is this a DIY job? Link to comment Share on other sites More sharing options...

PhillyWilly Posted November 16, 2010 Share Posted November 16, 2010 How hard is it to replace the LCA bushings? Do the LCA's have to come completely off the car? Is this a DIY job? Since you need to use a press to put them in, yes, they probably have to come off the car. I had mine done since I figured I would have to take the whole arm somewhere to press them in anyway. If you have access to a press its not a bad DIY. Not sure if anyone has had luck getting them in correctly without a press... maybe there is a way?

kb2spn Posted November 16, 2010 Share Posted November 16, 2010 I have the Perrin LCA.........a little harsh but the handling trade off is well worth it,car is smooth on highways and ruff going across railroad tracks,multiple buts etc. I also have BC coilovers and Perrin 25mm sways so just imagine the extra harshness......love it.

integroid Posted November 16, 2010 Share Posted November 16, 2010 I have the Perrin's as well and love them. Yes they are harsher but well worth it IMHO. The isntall isn't that hard if you have a press. Took me about an hour on my car for both sides. Link to comment Share on other sites More sharing options...

GTLEGACY007 Posted November 17, 2010 Author Share Posted November 17, 2010 Another note on this- replaced my stock wheels/tires with off-brand tires with some 18" Rotas and Hankook Ventus V12s and there was a BIG reduction in harshness with the new, nicer tires. I probably would not have started this thread at all had I had this wheel/tire setup on the car when I got the bushings installed. Link to comment Share on other sites More sharing options...
BAC5.2 Posted November 17, 2010 Share Posted November 17, 2010 Hmm, I'm torn between Whiteline and SuperPRO. I like the ability to adjust caster, but I have no desire to run anything but the maximum amount.

RayC Posted December 1, 2010 Share Posted December 1, 2010 Can you replace just this bushing w/o upgrading other bushings? Ie- will this increased firmness place more stress on other parts of the front suspension? Link to comment Share on other sites More sharing options...
PhillyWilly Posted December 1, 2010 Share Posted December 1, 2010 ^ Dont know what, if any stress will be placed on other components but I would assume its negligible. I think most of us have upgraded LCA bushings without upgrading others, myself included. Link to comment Share on other sites More sharing options...

RayC Posted December 2, 2010 Share Posted December 2, 2010 Thanks. I'll get both. edit: fredbeansparts has some good prices, i also got the shifter mount, bushings, and engine clippy things that for some reason disappear. Course i should have did the whole thing in one order instead of two... doh! Link to comment Share on other sites More sharing options...
PhillyWilly Posted December 3, 2010 Share Posted December 3, 2010 fredbeansparts has some good prices, i also got the shifter mount, bushings, and engine clippy things that for some reason disappear. Fredbeans is tough to beat. Ive probably bought 90% of my mods there. Shifter bushings make a nice difference. What is the shifter mount? Also highly recommend group n tranny mount and crossmember bushings. Link to comment Share on other sites More sharing options...
RayC Posted December 4, 2010 Share Posted December 4, 2010 The shifter mount is the Group N one. It was one of those "while i'm shopping i might as well..." purchases. The shifter bushings are kartboy. For control arm bushings i'm going with the whiteline front and AVO .5 degree rears. I have a press and all that so i'm not anticipating too much trouble. Couple questions - and i dont mean to hijack this thread so mods please move this post if you feel it appropriate. 1. What are common issues run into when pulling the control arms? Any tips? 2. What are the torque specs for the control arm bolts and anything i'm going to disconnect? Loc-tite required on anything? 3. Any tips for the shifter bushings? I have been only driving my subaru and working on my xr4ti - (doing a built bottom end this off season - mating to my esslinger (worked) d port aluminum head and fabbing up a custom intake manifold as well as scheduling some dyno time to get the stand alone dialed in... But the daily needs some lovin' so i'm getting some lovin' done. I need the legacy, the XR is a toy. Link to comment Share on other sites More sharing options...
RayC Posted December 16, 2010 Share Posted December 16, 2010 In case anyone was interested - slight update. Did the bushings and shifter mount last weekend. Turns out the front LCA bushing doesn't fit in my press so i am going to my buddy's shop (he's a subaru guru) tonight to do those. He's got some special arbor for it. Shifter mount and bushing (stock) were surprisingly soft rubber. The feedback change with the new mount and bushings is amazing. for the LCA (rear) bushing i've noticed barely any increase in NVH but noticed much less bump feedback thru the steering wheel and car itself.
