Eddie Trickett Posted July 12, 2021 Report Share Posted July 12, 2021 The previous owner fitted some long rear springs with over 9 coils. A loose pair with approximately 71/2 coils came with the car. I suspect they are original because the back of the car rides far too high. Will I have to remove the drive shaft bolts to get enough movement to remove these extra long springs?

stuart Posted July 12, 2021 Report Share Posted July 12, 2021 They will often come out with a tyre lever just be careful, If you remove the shock drop link then the arm will drop a bit more until the drive shaft touches the chassis, dont do this if you have CV jointed shafts as they will definitely need fully removing. If you do remove the drive shaft dont forget the hub to arm stud nuts are only 16ftlbs torque. Stuart. Quote Link to post Share on other sites
Rob Salisbury Posted July 12, 2021 Report Share Posted July 12, 2021 C/V shafts?, ....... remove the big outer hub nut ( it's tight! .. a couple of hundred foot/lbs or so) and push the shaft inwards as you lower the suspension arm then it works. Cheers Rob Quote Link to post Share on other sites
Motorsport Mickey Posted July 12, 2021 Report Share Posted July 12, 2021 (edited) Easier to prevent damage when removing the bump stops to unbolt the CV driveshafts fully from the inner end of the diff drive flange. Then let the shaft and hubs droop to their fullest extent to let you gain most access space. Warning … this is what Stuart is referring to in his post. If the driveshaft droop isn’t constrained by the bump stops, when the bump stops are removed the CV driveshafts WILL overexpand allowing their drive faces to be misaligned and mangled by turning forces when all is bolted back up and the car run… a number of failures caused by this in the Register.

Rob Salisbury Posted July 12, 2021 Report Share Posted July 12, 2021 The outer C/V joint slides in on the splines (as it does when you are assembling the shaft) and gives sufficient maneuvering room to fully lower the suspension arm without over-extending the shaft, ...... well it does on my car with TRNord C/V shafts, obviously the lowering is done in a controlled manor, a hydraulic jack or similar helps greatly here.

Andy Moltu Posted July 19, 2021 Report Share Posted July 19, 2021 This applies to jacking up cars with CV jointed drive shafts -if you jack up by the chassis alone and remove the shocker the force of the spring over extends the joint. Jack up by the trailing arm and release at either end - the big hub nut is done up to 215ftlbs and needs more than this to undo it. Probably easier to undo at the inner end which allows the trailing arm to drop without applying force to the drive shaft and allow spring removal. If it doesn't then the only option is to undo the hub nut but that's a struggle sometimes. Quote Link to post Share on other sites
