Rustina 510 Posted October 28, 2011 Report Share Posted October 28, 2011 So let's say I have a Datsun and when I drive it above 50mph I get wabbles like when your going to fast on a skateboard, Granted the shocks are totally shot? Is that all it is? Quote Link to comment
Rustina 510 Posted October 28, 2011 Author Report Share Posted October 28, 2011 And its backfiring super bad Quote Link to comment
INDY510 Posted October 28, 2011 Report Share Posted October 28, 2011 . does it feel like the front or back wheels??? ...... . any chance your tires are way off balance?,,, or is this a new problem?? ... check yo lug nuts ...... ;) Quote Link to comment
Laecaon Posted October 28, 2011 Report Share Posted October 28, 2011 I had this problem on Oregon freeways until I switched to ZX struts. I also hear lowering helps or a airdam. And backfiring/no power, if points check the condenser. Otherwise its just timing. Quote Link to comment
bananahamuck Posted October 28, 2011 Report Share Posted October 28, 2011 Switch the wheels around front to back, maybe side to side and see if feeling changes.. I have a 88 supra turbo that the tread is separating and it moves( wobbles) side to side, not shake. Quote Link to comment
Rustina 510 Posted October 28, 2011 Author Report Share Posted October 28, 2011 Th guys, I'll throw my coilovers on it and see how she does, Planning in upgrading dizzy and redoing the timing this weekend Quote Link to comment
Laecaon Posted October 28, 2011 Report Share Posted October 28, 2011 Basically to me it seems the car is too narrow. I have driven with the FR wheel in the right rut and the RL wheel in the Left rut. I was going down the freeway sideways... Wider wheels help too. Quote Link to comment
INDY510 Posted October 28, 2011 Report Share Posted October 28, 2011 . Check your front caster . . is it easier to turn one direction??? ... . . . . . . .... . . . . have you checked your front wheel bearings? Quote Link to comment
HRH Posted October 28, 2011 Report Share Posted October 28, 2011 It wabbles? Is that anything like wobbling? ;) Check your shocks. My 510 with crap original struts used to do the same thing. Either that or really bad wheel balance. Quote Link to comment
Bleach Posted October 28, 2011 Report Share Posted October 28, 2011 Wait, you drove a Datsun over 50mph?? :blink: Quote Link to comment

dennis Posted October 28, 2011 Report Share Posted October 28, 2011 so many things can cause the wobbles. If your car has been sitting for a long time then you could have flat spots on your tires. Like Indy said you could have out of balance tires. Shocks could be the cause as well. When I troubleshoot I always start with the cheapest items and work my way to the most expensive repair.

Rustina 510 Posted October 28, 2011 Author Report Share Posted October 28, 2011 Well I have a nice set of 510keeper front coilovers so I'll slap those babies on it and see how she rolls Quote Link to comment
datzenmike Posted October 29, 2011 Report Share Posted October 29, 2011 Flat spot tires will vibrate not really 'sway'. Swaying can be tires but usually a steering /suspension thing. Mixing tire sizes and brands can cause 'swaying'. Improper air pressure and cause it. Soft shocks or struts. Broken springs. Broken sway bar links. Front or rear misalignment. Worn steering box or steering components. Backfire?? Like out the tailpipe of the air filter??? Quote Link to comment
Dirk Diggler Posted October 29, 2011 Report Share Posted October 29, 2011 My work van had the same problem, we changed the ball joints and cv joints and it fixed it. It's not likely on a car, but on my quad if the tire pressure isn't even it will get the wobbles. Quote Link to comment
Rustina 510 Posted October 29, 2011 Author Report Share Posted October 29, 2011 Ok, been looking into the front suspension and this is what I found. It looks as though the camber or caster " can't remember wich is Wich" and the bottom of the front tires are much closer together than the top of the front tires, the steering seems good and tight, the tie rods look reAlly good and the shocks are cashed. So I'm thinking new shocks "already have them" and new lca bushings and new balljoints should fix just about everything in the front. Did some tuning to the carb and made some adjustments and got some good results but I'm thinkin the backfiring and misfiring is the timing So. Does anyone have a 69 five10 lca bushing kit and some balljoints I can buy? Quote Link to comment
izzo Posted October 29, 2011 Report Share Posted October 29, 2011 i gave you the part number and link to the lower control arm bushings from enegery suspension. 14 bucks man. Get moog ball joints, they are a little more pricey but will out last anything else. Quote Link to comment
datzenmike Posted October 29, 2011 Report Share Posted October 29, 2011 Wheels tilting in or out at the top is camber. Wheels tilting out at the top are said to have positive camber. The camber is built into the car (McPherson struts ) and not really adjustable. Lowering the car body will add negative camber, raising will increase positive camber or another way to look at it... lowering will tilt the top inwards and raising will tilt it out. Adding 280zx struts to many cars like the 510 and 610/710 will add positive camber (tilt the top outwards) Quote Link to comment
Rustina 510 Posted October 29, 2011 Author Report Share Posted October 29, 2011 Well the front is rather high, could that really be all that it is datsunmike? If I lower the front then it will level out right? Because then I'll just start with my awesome 510keeper front coilover set up and see where it sits after I'm done Quote Link to comment
Rustina 510 Posted October 30, 2011 Author Report Share Posted October 30, 2011 ? Ok then, the day is mine, I'm dropping the front suspension and we will see if the helps the camber and keeps the speed wabbles from happening Quote Link to comment
510kevin Posted October 30, 2011 Report Share Posted October 30, 2011 ? Ok then, the day is mine, I'm dropping the front suspension and we will see if the helps the camber and keeps the speed wabbles from happening is it done yet? :P Quote Link to comment
Laecaon Posted October 30, 2011 Report Share Posted October 30, 2011 is it done yet? :P Im going over some time soon... Quote Link to comment
ripetomatoes Posted October 30, 2011 Report Share Posted October 30, 2011 you should totally get some weebles, dude. Quote Link to comment
datzenmike Posted October 30, 2011 Report Share Posted October 30, 2011 Well the front is rather high, could that really be all that it is datsunmike? If I lower the front then it will level out right? Because then I'll just start with my awesome 510keeper front coilover set up and see where it sits after I'm done Easy to say but much more to it. The strut also has the equivalent of a shock absorber inside. If you lower too far it will reach the bottom of it's travel on a bump and bottom out. This will damage it. On a stock 510 strut you can counter this by increasing the spring rate, (make it stiffer) so it's harder to bottom out, but the ride can suffer. The next thing is to use a strut that is shorter but has about the same overall travel but allows the car to sit lower. 280zx struts are shorter by a inch or two and the car will sit lower by that amount (zx struts also have the advantage of having much larger calipers and vented rotors).... but the springs are too large a diameter and won't fit the 510. You can use the stock springs or add coil-overs. The zx struts will add positive camber so you will need camber plates that bolt to the strut mount tops and allow the strut tube to be moved inward to remove + camber. You can also get shorter removable strut inserts (shocks) and cut and remove some of the strut length and weld back up to match. A lot of work. Hey, I'll say right here I'm no expert on strut modifications and I've most likely left some stuff out. I have put zx struts (Maxima wagon struts actually, but the zx and Maxima share the same car platform and similar suspension components) on my 710 which has a similar front to the 510. Have the struts been swapped perhaps??? Pictures of the strut/caliper/rotor?? Quote Link to comment
