Hello. It seems the lower motor mount(s) are worn out; causing the engine to shift forward, coming in contact with the suspension parts. This 'shifting' is quite dangerous and can cause parts to 'clash' together. Good luck and keep me informed; if you want to.
First thing is to get safety glasses,block wheels securely !!...set emergency brake..,get a good flashlight.Disconnect negative battery cable...Some can wear inside the steering column,some can be a worn linkage cable ...The lever on the transmission located under vehicle Trans at lower part of trans,driver side can become loose or possibly damaged...First get under vehicle with safety glasses and observe operation of the lever where shift cable is mounted while assistant puts it in park...make sure the trans shift lever mounting nut is tight before shifting..If assistant can't get it in park use your hand and push forward on the linkage arm and it should go into park manually...If this is the problem you need to change shift cable...Some wear inside the column where steering wheel is mounted..If cab shifter feels very loose ..You will have to remove steering wheel and column cover to inspect."..The cable runs from trans to the steering column..Look between gas and brake pedal and verify cable coming up through floor board and runs to steering column...Double check shifter lever at trans is tight because it is mounted on a splined stud and it can strip the stud threads if it becomes loose..If loose remove lever and inspect splines for damage..Call dealer and make sure they have the part..Remove old cable from trans and put it in park with your hand...Remove and replace cable..Be sure lever inside cab and lever on the trans are both fully engaged into park while cable is removed before installing new cable....Attach new cable.....
I put one in a 1970 Chevelle. I bought the hand choke cable with pull lever and under dash mounting bracket. Mounted pull lever under the dash, drilled a hole in the firewall as high as I could, ran the cable out to the engine compartment. Mounted the holding bracket to the motor as close to carb as possible on the intake, then attached to the choke arm that works the butterfly plate in the carb throat. Cut to fit as tight as possible with butterfly plate closed and push lever all the way in. As you pull the hand lever out inside the car, it opens the butterfly plate to achieve the optimum air fuel mixture you desire to make the engine run smoothly. Sometimes you must go the opposite, lever out and plate closed, depending on the way the carb is set up, and work it the opposite way.
Hi, if you have the 3.0 liter engine, see instructions below. If you have the 4.6 liter, the starter is under the intake manifold.
Removal & Installation
Before servicing the vehicle, refer to the Precautions Section.
Remove or disconnect the following:
Negative battery cableStarter electrical connectorsRight hand catalytic converterRight side engine mount nutsIntake air resonator to the throttle body ducts
Install an Engine Support Fixture to the right side of the engine.
Raise the right side of the engine approximately 1.5 inches (38mm) to gain access to the starter motor bolts.
Remove or disconnect the following:
Engine mount from the bracket and cradleEngine mount bracket bolts and reposition the bracketStarter motor
Fig. Remove the starter motor and bolts
To install:
Install or connect the following:
Starter motor. Torque the bolts to 44 ft. lbs. (60 Nm).Engine mount to the bracket and front crossmember. Torque the bolts to 30 ft. lbs. (40 Nm).
Lower the engine into position and make certain that the mount locator tab is fully seated in the front crossmember slot.
Remove the special tools from the engine.
Install or connect the following:
Engine mount nuts. Torque the upper nut to 30 ft. lbs. (40 Nm) and the lower nut to 41 ft. lbs. (55 Nm).Intake air resonator to the throttle body ductsCatalytic converter. Torque the bolt to 25 ft. lbs. (34 Nm) and the nuts to 18 ft. lbs. (25 Nm).Starter electrical connectors. Torque the battery cable nut to 115
inch lbs. (13 Nm) and the starter solenoid nut to 35 inch lbs. (4 Nm).Negative battery cable
Put the car on stands and put a jack within a few inches of the under side of the engine. Loosen the bolt mounts by about have a turn. Have a friend use a length of timber and use jack top as a lever fulcrum to take the weight of the engine off the mount whilst you remove the mounting bolts. Take care not to put any load on the oil pan as it can crush quite easily. You should be able to adjust the engine attitude about two inches without having to detach anything, this is enough room to get the old mount out and therefore the new one in. Take your time and keep safe
If the cruise control makes the engine seem to run very rough until disengaging it, there could be a problem with the engine itself. As, most cruise control systems just pull on the throttle cable to maintain speed on the highway based on setting the speed with the button.
So, I would look into the engine maybe having an issue with spark plugs, or wires, or another tuneup or mechanical issue.

On the Ironhead Sportster, the top motor mount bolt that goes through the frame is usually a 1/2 inch bolt. I'd use a grade 8 fine thread bolt with a nylok nut on it. Make sure you "shim" the top motor mount to the frame with the appropiate amount of washers so as not to "torque" the frame. If you do, either the top motor mount or the tab on the frame will break from the torque and vibration.
