stormchaser Posted June 27, 2021 Share Posted June 27, 2021 Hey everyone, I recently bought a used hobao hyper 7 TQ sport to scratch a nitro itch i have had for years now but when checking it over have noticed a possible problem with the front suspension. When the car is on the ground and you push down on the front end it doesn't spring back up at all it just stays compressed and you have to lift it back up by hand, I have removed the shocks today and cant see anything wrong at all there is plenty of oil inside and nothing is bent or leaking.I gave them both a bleed to remove any air but is still the same.It has the standard grey springs fitted .Surely thats not how they should be is it?

Stormbringer Posted June 27, 2021 Share Posted June 27, 2021 Use the threaded collar to add more preload to the springs or if it has the standard shocks there should be black plastic C clips in various thicknesses to add preload Quote Link to comment Share on other sites More sharing options...

Stormbringer Posted June 27, 2021 Share Posted June 27, 2021 If you lift the car up level about a foot of the floor then drop it does the arms end up level or nearly level ? Quote Link to comment Share on other sites More sharing options...
stormchaser Posted June 27, 2021 Author Share Posted June 27, 2021 The rear arms end up dead level and the front almost level Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 27, 2021 Share Posted June 27, 2021 its not far off then mate so wouldnt worry much about it but if you do come across some more C clips you could add more Quote Link to comment Share on other sites More sharing options...
stormchaser Posted June 27, 2021 Author Share Posted June 27, 2021 Will keep a look out for more clips then, so is it normal for them to be like this with no clips in ? Just seem a bit odd to me, the rear rises back up slowly but front just stays on the floor lol Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 27, 2021 Share Posted June 27, 2021 its just the springs didnt have enough preload on them it could be the springs have lost a bit of their springiness and arnt reacting as they should and providing the car isnt rubbing its nose along ground when being driven should be ok some of my cars if you push nose down they dont always rebound to level but nose does lift up a bit when released Quote Link to comment Share on other sites More sharing options...
stormchaser Posted June 27, 2021 Author Share Posted June 27, 2021 Ok will have to see what happens when drive it hopefully this week when fuel turns up. Do you have any idea what oil weight should be in these as doesnt say in the manual and am thinking mite be worth a change anyway. Quote Link to comment Share on other sites More sharing options...

Fuzzock Posted July 2, 2021 Share Posted July 2, 2021 I would also check if any of your pivot bolts are bent as that can really mess up the action. Ian... Quote Link to comment Share on other sites More sharing options...
